    Jossem, E. Leonard

    2007-09-01

    Physicist, polymath, educator, leader, Horace Richard Crane died on April 19, 2007, a few months short of his 100th birthday. Those of us who were fortunate enough to have had him as a friend mourn his loss, but for all of us he leaves a rich and varied legacy of published works that invite reading and rereading. Dick's work as a physicist was recognized in 1966 by his election to the National Academy of Sciences and in 1986 by the award of the President's National Medal of Science: "For the first measurement of the magnetic moment and spin of free electrons and positrons."

    Louis Dick, a CERN experimental physicist of international renown, passed away on 14 July.   Louis in his office, a veritable archaeological wonder with strata of documents corresponding to various eras of physics. Born in Geneva on 27 April 1921, Louis obtained a physics degree at ETH-Zurich in 1946 before moving to the Institut du Radium in Paris, where he joined the group led by Frédéric and Irène Joliot-Curie. He took a leave of absence in 1957 to go to CERN, where he remained until well beyond his retirement in 1986. In the late 1950s and early 1960s, Louis worked at CERN’s Synchrocyclotron (SC) and later on studies at the Proton Synchrotron (PS). When the first polarised proton target arrived at CERN from Saclay in 1963, Louis proposed using it for studies of spin effects in pion-proton elastic scattering at the PS, and between 1964 and 1966 sizeable spin effects were found. Louis and his collaborators then continued these studies wi...

    A detailed non-linear analysis of the internal structure of spherical, charged black holes that are accreting scalar matter is performed in the framework of the Brans-Dicke theory of gravity. We choose the lowest value of the Brans-Dicke parameter that is compatible with observational constraints. First, the homogeneous approximation is used. It indicates that mass inflation occurs and that the variations of the Brans-Dicke scalar inside the black hole, which could in principle be large in th...

    2017-01-01

    This article demonstrates how the influential scholar Edgar Dale, alongside a generation of educational technologists, helped build an essential place for AV materials and pedagogical methods in the American classroom. It also shows that, for decades, the Payne Fund philanthropy supported multimedia research agendas that shaped ideas about teaching and technology, far beyond involvement in their famed studies on motion pictures and children in the 1930s. With his writings and research programs, Dale advanced concepts of media experience and systematicity, which came to be understood as common sense to the information society. In so doing he was a leading contributor to the discursive and ideological structure of our age of technological and informational abundance.

  16. Functional methods in the generalized Dicke model

    International Nuclear Information System (INIS)

    Alcalde, M. Aparicio; Lemos, A.L.L. de; Svaiter, N.F.

    2007-01-01

    The Dicke model describes an ensemble of N identical two-level atoms (qubits) coupled to a single quantized mode of a bosonic field. The fermion Dicke model should be obtained by changing the atomic pseudo-spin operators by a linear combination of Fermi operators. The generalized fermion Dicke model is defined introducing different coupling constants between the single mode of the bosonic field and the reservoir, g 1 and g 2 for rotating and counter-rotating terms respectively. In the limit N -> ∞, the thermodynamic of the fermion Dicke model can be analyzed using the path integral approach with functional method. The system exhibits a second order phase transition from normal to superradiance at some critical temperature with the presence of a condensate. We evaluate the critical transition temperature and present the spectrum of the collective bosonic excitations for the general case (g 1 ≠ 0 and g 2 ≠ 0). There is quantum critical behavior when the coupling constants g 1 and g 2 satisfy g 1 + g 2 =(ω 0 Ω) 1/2 , where ω 0 is the frequency of the mode of the field and Ω is the energy gap between energy eigenstates of the qubits. Two particular situations are analyzed. First, we present the spectrum of the collective bosonic excitations, in the case g 1 ≠ 0 and g 2 ≠ 0, recovering the well known results. Second, the case g 1 ≠ 0 and g 2 ≠ 0 is studied. In this last case, it is possible to have a super radiant phase when only virtual processes are introduced in the interaction Hamiltonian. Here also appears a quantum phase transition at the critical coupling g 2 (ω 0 Ω) 1/2 , and for larger values for the critical coupling, the system enter in this super radiant phase with a Goldstone mode.

    We analyse the fate of density perturbation in the Brans-Dicke Theory, giving a general classification of the solutions of the perturbed equations when the scale factor of the background evolves as a power law. We study with details the cases of vacuum, inflation, radiation and incoherent matter. We find, for the a negative Brans-Dicke parameter, a significant amplification of perturbations.

  20. Directional Dicke Subradiance with Nonclassical and Classical Light Sources

    Science.gov (United States)

    Bhatti, Daniel; Schneider, Raimund; Oppel, Steffen; von Zanthier, Joachim

    2018-03-01

    We investigate Dicke subradiance of N ≥2 distant quantum sources in free space, i.e., the spatial emission patterns of spontaneously radiating noninteracting multilevel atoms or multiphoton sources, prepared in totally antisymmetric states. We find that the radiated intensity is marked by a full suppression of spontaneous emission in particular directions. In resemblance to the analogous, yet inverted, superradiant emission profiles of N distant two-level atoms prepared in symmetric Dicke states, we call the corresponding emission patterns directional Dicke subradiance. We further derive that higher-order intensity correlations of the light emitted by statistically independent thermal light sources display the same directional Dicke subradiant behavior and show that it stems from the same interference phenomenon as in the case of quantum sources. We finally present measurements of directional Dicke subradiance for N =2 ,…,5 distant thermal light sources corroborating the theoretical findings.

  1. Thermodynamics of black-holes in Brans-Dicke gravity

    Kim, H.; Kim, Y.

    1997-01-01

    It is recently been argued that non-trivial Brans-Dicke black-hole solutions different from the usual Schwarzschild solution could exist. The authors attempt here to 'censor' these non-trivial Brans-Dicke black-hole solutions by examining their thermodynamics properties. Quantities like Hawking temperature and entropy of the black holes are computed. The analysis of the behaviors of these thermodynamic quantities appears to show that even in Brans-Dicke gravity, the usual Schwarzschild space-time turns out to be the only physically relevant uncharged black-hole solution

    In this short note we report our finding that within the context of alternative version of the Brans-Dicke theory (for ω ≥ -3/2, where ω is the Brans-Dicke parameter) the anisotropic Bianchi type cosmological models evolve towards the de Sitter isotropic universe. In short it is shown that during inflation there is no difference between the Brans-Dicke theory and General Relativity. Our result can thus be viewed as a generalization of the Wald's theorem for General Relativity. (author). 5 refs

  3. Explaining fast radio bursts through Dicke's superradiance

    Science.gov (United States)

    Houde, Martin; Mathews, Abhilash; Rajabi, Fereshteh

    2018-03-01

    Fast radio bursts (FRBs), characterized by strong bursts of radiation intensity at radio wavelengths lasting on the order of a millisecond, have yet to be firmly associated with a family, or families, of astronomical sources. It follows that despite the large number of proposed models, no well-defined physical process has been identified to explain this phenomenon. In this paper, we demonstrate how Dicke's superradiance, for which evidence has recently been found in the interstellar medium, can account for the characteristics associated with FRBs. Our analysis and modelling of previously detected FRBs suggest they could originate from regions in many ways similar to those known to harbour masers or megamasers, and result from the coherent radiation emanating from populations of molecules associated with large-scale entangled quantum mechanical states. We estimate this entanglement to involve as many as ˜1030 to ˜1032 molecules over distances spanning 100-1000 au.

  4. Einstein metrics and Brans-Dicke superfields

    International Nuclear Information System (INIS)

    Marques, S.

    1988-01-01

    It is obtained here a space conformal to the Einstein space-time, making the transition from an internal bosonic space, constructed with the Majorana constant spinors in the Majorana representation, to a bosonic ''superspace,'' through the use of Einstein vierbeins. These spaces are related to a Grassmann space constructed with the Majorana spinors referred to above, where the ''metric'' is a function of internal bosonic coordinates. The conformal function is a scale factor in the zone of gravitational radiation. A conformal function dependent on space-time coordinates can be constructed in that region when we introduce Majorana spinors which are functions of those coordinates. With this we obtain a scalar field of Brans-Dicke type. 11 refs

  5. Optimized entanglement witnesses for Dicke states

    Quantum entanglement is an important resource for applications in quantum information processing like quantum teleportation and cryptography. Moreover, the number of particles that can be entangled experimentally using polarized photons or ion traps has been significantly enlarged. Therefore, criteria to decide the question whether a given multi-particle state is entangled or not have to be improved. Our approach to this problem uses the notion of PPT mixtures which form an approximation to the set of bi-separable states. With this method, entanglement witnesses can be obtained in a natural manner via linear semi-definite programming. In our contribution, we will present analytical results for entanglement witnesses for Dicke states. This allows to overcome the limitations of convex optimization.

  6. The correspondence of Thomas Dale (1700-1750): Botany in the transatlantic Republic of Letters.

    Science.gov (United States)

    Cook, William J

    2012-03-01

    This paper seeks to provide a full account of the life and career of Dr. Thomas Dale (1700-1750), with particular reference to his botanical works and correspondence. Born in Hoxton, London, Dale studied medicine at Leiden and engaged fully in the social, literary and epistolary network in which botany was practised in eighteenth-century England. In 1730, however, Dale relocated to the British colonial port of Charles Town, South Carolina. Here he continued to engage in a transatlantic network of botanical exchange and discussion, corresponding on equal and reciprocal terms with his former colleagues in England. Where Dale differs from naturalists in South Carolina before him is that his motives for pursuing botany and for corresponding with English naturalists were located firmly in the New World. Such a conclusion forms a valuable, albeit small contribution to models for the development of national scientific cultures in the imperial world. Similarly, Dale's pursuit of botanical information in South Carolina provides a small amount of material with which to illustrate currently fashionable models for the mediated exchange and circulation of scientific knowledge.

  7. Aspects of a supersymmetric Brans-Dicke theory

    Energy Technology Data Exchange (ETDEWEB)

    Catena, R.

    2006-11-15

    We consider a locally supersymmetric theory where the Planck mass is replaced by a dynamical superfield. This model can be thought of as the Minimal Supersymmetric extension of the Brans-Dicke theory (MSBD). The motivation that underlies this analysis is the research of possible connections between Dark Energy models based on Brans-Dicke-like theories and supersymmetric Dark Matter scenarios. We find that the phenomenology associated with the MSBD model is very different compared to the one of the original Brans-Dicke theory: the new scalar and fermionic degrees of freedom do not couple to matter in a universal metric way, i.e. they can not be removed from the matter sector by a Weyl rescaling of the metric. This feature could make the minimal supersymmetric extension of the BD idea phenomenologically inconsistent. (orig.)

    We consider the Brans-Dicke theory motivated by the f(R)=R+αR{sup n}−βR{sup 2−n} model to obtain a stable minimum of the Einstein frame scalar potential of the Brans-Dicke field. As a result we have obtained an inflationary scalar potential with non-zero value of residual vacuum energy, which may be a source of dark energy. In addition we discuss the probability of quantum tunnelling from the minimum of the potential. Our results can be easily consistent with PLANCK or BICEP2 data for appropriate choices of the value of n and ω.

    Atazadeh, K. [Shahid Beheshti University G. C., Evin, Department of Physics, Tehran (Iran, Islamic Republic of)

    2011-04-15

    In the standard picture of cosmology, when the universe was about 10 {mu}sec old it underwent a transition from quark phase to hadron one, being associated with a chiral symmetry breaking after the electro weak transition. We assume that this transition was of crossover and study the evolution of the Universe in the context of Brans-Dicke theory. The evolution of physical quantities relevant to the physical description of the early Universe, namely, the energy density, temperature and the scale factor, are studied within an effective model of lattice QCD for high temperature and also we consider in the context of hadronic resonance gas model those parameters at low temperature. We show that for different values of Brans-Dicke coupling, {omega}, a phase transition occurs and results in decreasing of the effective temperature of the quark-gluon plasma during the process of quark-hadron phase transition.

  17. Interacting holographic dark energy in Brans-Dicke theory

    International Nuclear Information System (INIS)

    Sheykhi, Ahmad

    2009-01-01

    We study cosmological application of interacting holographic energy density in the framework of Brans-Dicke cosmology. We obtain the equation of state and the deceleration parameter of the holographic dark energy in a non-flat universe. As system's IR cutoff we choose the radius of the event horizon measured on the sphere of the horizon, defined as L=ar(t). We find that the combination of Brans-Dicke field and holographic dark energy can accommodate w D =-1 crossing for the equation of state of noninteracting holographic dark energy. When an interaction between dark energy and dark matter is taken into account, the transition of w D to phantom regime can be more easily accounted for than when resort to the Einstein field equations is made.

    We propose the analog-digital quantum simulation of the quantum Rabi and Dicke models using circuit quantum electrodynamics (QED). We find that all physical regimes, in particular those which are impossible to realize in typical cavity QED setups, can be simulated via unitary decomposition into digital steps. Furthermore, we show the emergence of the Dirac equation dynamics from the quantum Rabi model when the mode frequency vanishes. Finally, we analyze the feasibility of this proposal under realistic superconducting circuit scenarios.

    Science.gov (United States)

    Pier, Jeffrey R.; Mason, Brian

    2005-12-01

    Dick Walker, 67, died 30 March 2005 in Flagstaff, AZ, following a long illness. He was born on 9 March 1938 in Hampton, Iowa and grew up in Waterloo, Iowa. As a child, Dick was fascinated with astronomy and built his own telescope. He saved his pennies and bought and read every book on the subject he could find. He also raised pigeons, naming four of them Hertzsprung, Hoyle, Gamow, and Kron. In 1957, the year Sputnik was launched, Dick began his college studies at the University of Northern Iowa in Cedar Falls. In 1959, he transferred to the State University of Iowa (subsequently renamed the University of Iowa) in Iowa City, where he earned a BA degree in astronomy and physics in 1963. He joined the staff of the U.S. Naval Observatory in Washington, DC, where he worked in the Time Service Division for a year before his assignment to the Astrometry and Astrophysics Division. Dick relocated to Flagstaff, AZ, in 1966 to continue his Naval Observatory service at the Flagstaff Station. His retirement in May 1999, ended a thirty-six-year career with USNO. Dick was first and foremost an observational astronomer. From the mid 1960s through the late 1970s, much of Dick's time was devoted to the measurement of binary stars, observing with the 12-inch and 26-inch refractors in Washington and later the 40-inch and 61-inch reflectors in Flagstaff. He also made many trips to Lick Observatory to work with the 36-inch Clark Refractor there. During this time he consulted with Charles Worley, who was observing on the 26-inch, to make sure time was well-spent examining doubles that could not be observed in Washington. This period of observing overlapped with the early years of speckle interferometry, and Dick's observations, made with the largest telescope used for micrometry at the time, were very important for ascertaining the veracity of this new technique. He was a studious and very careful observer of doubles and made over 8,000 measures, resulting in almost 3,000 mean positions

    We experimentally investigate the Dicke phase transition in chaotic optical resonators realized with two-dimensional photonics crystals. This setup circumvents the constraints of the system originally investigated by Dicke and allows a detailed study of the various properties of the superradiant transition. Our experimental results, analytical prediction, and numerical modeling based on random-matrix theory demonstrate that the probability density P? of the resonance widths provides a new criterion to test the occurrence of the Dicke transition.

    We obtain geodesically complete spacetimes generated by static and rotating magnetic point sources in an Einstein-Maxwell-Dilaton theory of the Brans-Dicke type in three dimensions (3D). The theory is specified by three fields, the dilaton, the graviton and the electromagnetic field, and two parameters, the cosmological constant and the Brans-Dicke parameter, w. When the Brans-Dicke parameter is infinity, our solution reduces to the magnetic counterpart of the BTZ solution, while the w=0 case...

  3. Do massive Brans-Dicke theories of gravitation imitate Brans-Dicke theories with nonzero divergence of energy-momentum tensor

    Acharya and Hogan (1973) have introduced a massive scalar field into the usual Brans-Dicke (1961) theory of gravitation. Formally they obtain certain field equations. The assumption of a nonzero divergence for T mu nu (or equivalently the introduction of sources) formally imitates a massive Brans-Dicke and satisfies the condition of Acharya and Hogan that the theory be indistinguishable with the classical test of the Einstein theory. Although it was shown elsewhere that the modified Brans-Dicke theory agrees with the classical test under certain conditions, there were no specified limits on omega, a similar circumstance discovered by Acharya and Hogan for the massive scalar field.

    An exact solution of straight spinning cosmic strings in Brans-Dicke theory of gravitation is presented. The possibility of the existence of closed time-like curves around these cosmic strings is analyzed. Furthermore, the stability about the formation of the topological defect discussed here is checked. It is shown that the existence of a suitable choice for the integration constants in which closed time-like curves are not allowed. We also study the (im)possibility of using the obtained spacetime in the rotational curves problem.

    Motivated by the recent work of one of us Setare and Jamil (2010) , we generalize this work to the case where the pressureless dark matter and the holographic dark energy do not conserve separately but interact with each other. We investigate the cosmological applications of interacting holographic dark energy in Brans-Dicke theory with chameleon scalar field which is non-minimally coupled to the matter field. We find out that in this model the phantom crossing can be constructed if the model parameters are chosen suitably. We also perform the study for the new agegraphic dark energy model and calculate some relevant cosmological parameters and their evolution.

    The supreme accuracy of atomic clocks relies on the universality of atomic transition frequencies. The stability of a clock, meanwhile, measures how quickly the clock's statistical uncertainties are reduced. The ultimate measure of stability is provided by the quantum projection noise, which improves as 1/√N by measuring N uncorrelated atoms. Quantum projection noise limited stabilities have been demonstrated in caesium clocks and in single-ion optical clocks, where the quantum noise overwhelms the Dick effect attributed to local oscillator noise. Here, we demonstrate a synchronous frequency comparison of two optical lattice clocks using 87Sr and 88Sr atoms, respectively, for which the Allan standard deviation reached 1 × 10-17 in an averaging time of 1,600 s by cancelling out the Dick effect to approach the quantum projection noise limit. The scheme demonstrates the advantage of using a large number (N ~ 1,000) of atoms in optical clocks and paves the way to investigating the inherent uncertainties of clocks and relativistic geodesy on a timescale of tens of minutes.

    Recently the most general completion of Brans-Dicke theory has appeared with energy exchanged between the scalar field and ordinary matter, given that the equation of motion for the scalar field keeps the simple wave form of Brans-Dicke. This class of theories contain undetermined functions, but there exist only three theories which are unambiguously determined from consistency. Here, for the first such theory, the action of the vacuum theory is found, which arises as the limit of the full matter theory. A symmetry transformation of this vacuum action in the Jordan frame is found which consists of a conformal transformation of the metric together with a redefinition of the scalar field. Since the general family of vacuum theories is parametrized by an arbitrary function of the scalar field, the action of this family is also found. As for the full theory with matter the action of the system is only found when the matter Lagrangian vanishes on-shell, as for example for pressureless dust. Due to the interaction, the matter Lagrangian is non-minimally coupled either in the Jordan or the Einstein frame. (orig.)

    In the Brans-Dicke theory the Planck mass is replaced by a dynamical scalar field. We consider here the supersymmetric analogous of this mechanism replacing in the supergravity Lagrangian the Planck mass with a chiral superfield. This analysis is motivated by the research of possible connections between supersymmetric Dark Matter scenarios and Dark Energy models based on Brans-Dicke-like theories. We find that, contrary to the original Brans-Dicke theory, in its supersymmetric analogous the gravitational sector does not couple to the matter sector in a universal metric way. As a result, violations of the weak equivalence principle could be present in such a scenario. (orig.)

    The Dick effect is one of the main limits to the frequency stability of a passive frequency standard, especially for the fountain clock and ion clock operated in pulsed mode which require unavoidable dead time during interrogation. Here we measure the phase noise of the interrogation oscillator applied in the microwave frequency standard based on laser-cooled 113Cd+ ions, and analyze the Allan deviation limited by the Dick effect. The results indicate that the Dick effect is one of the key issues for the cadmium ion clock to reach expected frequency stability. This problem can be resolved by interrogating the local oscillator continuously with two ion traps.

    Gravitational collapse of the Brans-Dicke scalar field with non-zero potential in the presence of matter fluid obeying the barotropic equation of state, p = wrho, is studied. Utilizing the concept of the expansion parameter, it is seen that the cosmic censorship conjecture may be violated for w=-1/3 and w=-2/3 which correspond to the cosmic string and domain wall, respectively. We have shown that physically, it is the rate of collapse that governs the formation of a black hole or a naked singularity as the final fate of dynamical evolution and only for these two cases can the singularity be naked as the collapse end state. Also the weak energy condition is satisfied by the collapsing configuration.

    Gravitational radiation is an excellent field for testing theories of gravity in strong gravitational fields. The current observations on the gravitational-wave (GW) bursts by LIGO have already placed various constraints on the alternative theories of gravity. In this paper, we investigate the possible bounds which could be placed on the Brans-Dicke gravity using GW detection from inspiraling compact binaries with the proposed Einstein Telescope, a third-generation GW detector. We first calculate in detail the waveforms of gravitational radiation in the lowest post-Newtonian approximation, including the tensor and scalar fields, which can be divided into the three polarization modes, i.e., "plus mode," "cross mode," and "breathing mode." Applying the stationary phase approximation, we obtain their Fourier transforms, and derive the correction terms in amplitude, phase, and polarization of GWs, relative to the corresponding results in general relativity. Imposing the noise level of the Einstein Telescope, we find that the GW detection from inspiraling compact binaries, composed of a neutron star and a black hole, can place stringent constraints on the Brans-Dicke gravity. The bound on the coupling constant ωBD depends on the mass, sky position, inclination angle, polarization angle, luminosity distance, redshift distribution, and total observed number NGW of the binary systems. Taking into account all the burst events up to redshift z =5 , we find that the bound could be ωBD≳1 06×(NGW/1 04)1/2. Even for the conservative estimation with 1 04 observed events, the bound is still more than one order tighter than the current limit from Solar System experiments. So, we conclude that the Einstein Telescope will provide a powerful platform to test alternative theories of gravity.

  15. Responses of the Brans-Dicke field due to gravitational collapses

    We study responses of the Brans-Dicke field due to gravitational collapses of scalar field pulses using numerical simulations. Double-null formalism is employed to implement the numerical simulations. If we supply a scalar field pulse, it will asymptotically form a black hole via dynamical interactions of the Brans-Dicke field. Hence, we can observe the responses of the Brans-Dicke field by two different regions. First, we observe the late time behaviors after the gravitational collapse, which include formations of a singularity and an apparent horizon. Second, we observe the fully dynamical behaviors during the gravitational collapse and view the energy-momentum tensor components. For the late time behaviors, if the Brans-Dicke coupling is greater (or smaller) than -1.5, the Brans-Dicke field decreases (or increases) during the gravitational collapse. Since the Brans-Dicke field should be relaxed to the asymptotic value with the elapse of time, the final apparent horizon becomes time-like (or space-like). For the dynamical behaviors, we observed the energy-momentum tensors around {omega} {approx} -1.5. If the Brans-Dicke coupling is greater than -1.5, the T{sub uu} component can be negative at the outside of the black hole. This can allow an instantaneous inflating region during the gravitational collapse. If the Brans-Dicke coupling is less than -1.5, the oscillation of the T{sub vv} component allows the apparent horizon to shrink. This allows a combination that violates weak cosmic censorship. Finally, we discuss the implications of the violation of the null energy condition and weak cosmic censorship.

    Dicke state is an widely used type of multi-particle entangled state in quantum information. However, very few works have been done on its nonlocality. Here we prepare a four-photon symmetric Dicke state, whose fidelity is as high as 0.904 ± 0.004, and devise a simple Bell-type inequality to demonstrate that it violates the local realism with 12 standard deviation.

  19. The Critical Point Entanglement and Chaos in the Dicke Model

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available Ground state properties and level statistics of the Dicke model for a finite number of atoms are investigated based on a progressive diagonalization scheme (PDS. Particle number statistics, the entanglement measure and the Shannon information entropy at the resonance point in cases with a finite number of atoms as functions of the coupling parameter are calculated. It is shown that the entanglement measure defined in terms of the normalized von Neumann entropy of the reduced density matrix of the atoms reaches its maximum value at the critical point of the quantum phase transition where the system is most chaotic. Noticeable change in the Shannon information entropy near or at the critical point of the quantum phase transition is also observed. In addition, the quantum phase transition may be observed not only in the ground state mean photon number and the ground state atomic inversion as shown previously, but also in fluctuations of these two quantities in the ground state, especially in the atomic inversion fluctuation.

    "Dale's Principle" states that each neuron releases one and only one synaptic transmitter. Mental disorders and behavioral drug effects are attributed to activation or blockade of one or more of these specific transmitters. A series of biochemical, electrophysiological, and behavioral studies suggests the alternative view that at each monoaminergic synapse the action of the transmitter is modulated by several metabolically related substances: amine analogs (2-phenylethylamine [PEA], p-tyramine, etc.), deaminated products (aldehydes, acids, and alcohols), and possibly also amino acid precursors. In support of this view, the authors present evidence for the presence, synthesis, metabolism, and biological activity (at the cellular level, using microelectrode techniques) of amino acid, amines, and deaminated compounds metabolically related to catecholamines and sorotonin. That neuroamino acids exert direct effects (not mediated via their amine metabolites) is illustrated by the rapid effects of microiontophoretic dopa upon cortical unit activity, and by the observation that neither the lethargic effect of 5-hydroxytryptophan (considered to support Jouvet's serotonergic theory of sleep) nor the behavioral stimulant effects of dopa (considered to support the catecholamine theory of affective behavior) are significantly prevented by L-aromatic amino acid decarboxylase inhibitors. The biological activity of the deaminated metabolites of catecholamines and serotonin is illustrated by the effects of their microiontophoretic administration upon cortical units. Further, probenecid (an inhibitor of acid transport across the blood-brain barrier) is shown to qualitatively alter the effects of intraventricularly administered PEA and of its metabolite phenylacetic acid upon visual evoked potentials. Rabbit brain is shown to synthesize a series of pharmacologically active noncatecholic phenylethylamines as by-products of catecholamine metabolism. Amine modulators such as PEA differ

  1. Identification of a mutation associated with fatal Foal Immunodeficiency Syndrome in the Fell and Dales pony.

    Full Text Available The Fell and Dales are rare native UK pony breeds at risk due to falling numbers, in-breeding, and inherited disease. Specifically, the lethal Mendelian recessive disease Foal Immunodeficiency Syndrome (FIS, which manifests as B-lymphocyte immunodeficiency and progressive anemia, is a substantial threat. A significant percentage (∼10% of the Fell ponies born each year dies from FIS, compromising the long-term survival of this breed. Moreover, the likely spread of FIS into other breeds is of major concern. Indeed, FIS was identified in the Dales pony, a related breed, during the course of this work. Using a stepwise approach comprising linkage and homozygosity mapping followed by haplotype analysis, we mapped the mutation using 14 FIS-affected, 17 obligate carriers, and 10 adults of unknown carrier status to a ∼1 Mb region (29.8 - 30.8 Mb on chromosome (ECA 26. A subsequent genome-wide association study identified two SNPs on ECA26 that showed genome-wide significance after Bonferroni correction for multiple testing: BIEC2-692674 at 29.804 Mb and BIEC2-693138 at 32.19 Mb. The associated region spanned 2.6 Mb from ∼29.6 Mb to 32.2 Mb on ECA26. Re-sequencing of this region identified a mutation in the sodium/myo-inositol cotransporter gene (SLC5A3; this causes a P446L substitution in the protein. This gene plays a crucial role in the regulatory response to osmotic stress that is essential in many tissues including lymphoid tissues and during early embryonic development. We propose that the amino acid substitution we identify here alters the function of SLC5A3, leading to erythropoiesis failure and compromise of the immune system. FIS is of significant biological interest as it is unique and is caused by a gene not previously associated with a mammalian disease. Having identified the associated gene, we are now able to eradicate FIS from equine populations by informed selective breeding.

  2. Dynamic recrystallization mechanisms and their transition in the Daling Thrust (DT) zone, Darjeeling-Sikkim Himalaya

    2016-04-01

    The Daling Thrust (DT) delineates a zone of intense shear localization in the Lesser Himalayan Sequence (LHS) of the Darjeeling-Sikkim Himalaya. From microstructural studies of deformed quartzite samples, we show a transition in the dynamic recrystallization mechanism with increasing distance from the DT, dominated by grain boundary bulging (BLG) recrystallization closest to the DT, and progressively replaced by sub-grain rotation (SGR) recrystallization away from the thrust. The transition is marked by a characteristic variation in the fractal dimension (D) of grain boundaries, estimated from the area-perimeter method. For the BLG regime, D ≈ 1.046, which decreases significantly to a value as low as 1.025 for the SGR regime. Using the available thermal data for BLG and SGR recrystallization, we infer increasing deformation temperatures away from the DT in the hanging wall. Based on the quartz piezometer our estimates reveal strong variations in the flow stress (59.00 MPa to 16.00 MPa) over a distance of 1.2 km from the DT. Deformation mechanism maps constructed for different temperatures indicate that the strain rates (10- 12 S- 1 to 10- 14 S- 1) comply with the geologically possible range. Finally, we present a mechanical model to provide a possible explanation for the cause of stress intensification along the DT.

    We study a cosmological implication of holographic dark energy in the Brans-Dicke gravity. We employ the holographic model of dark energy to obtain the equation of state for the holographic energy density in non-flat (closed) universe enclosed by the event horizon measured from the sphere of horizon named L. Our analysis shows that one can obtain the phantom crossing scenario if the model parameter {alpha} (of order unity) is tuned accordingly. Moreover, this behavior is achieved by treating the Brans-Dicke scalar field as a Chameleon scalar field and taking a non-minimal coupling of the scalar field with matter. Hence one can generate phantom-like equation of state from a holographic dark energy model in non-flat universe in the Brans-Dicke cosmology framework.

    The dynamics of the Brans-Dicke theory with a scalar field potential function is investigated. We show that the system with a barotropic matter content can be reduced to an autonomous three-dimensional dynamical system. For an arbitrary potential function, we found the values of the Brans-Dicke parameter for which a global attractor in the phase space representing the de Sitter state exists. Using linearized solutions in the vicinity of this critical point, we show that the evolution of the Universe mimics the ΛCDM model. From the recent Planck satellite data, we obtain constraints on the variability of the effective gravitational coupling constant as well as the lower limit of the mass of the Brans-Dicke scalar field at the de Sitter state.

    The post Newtonian parameter is considered in the chameleon-Brans-Dicke model. In the first step, the general form of this parameter and also effective gravitational constant is obtained. An arbitrary function for f(Φ), which indicates the coupling between matter and scalar field, is introduced to investigate validity of solar system constraint. It is shown that the chameleon-Brans-Dicke model can satisfy the solar system constraint and gives us an ω parameter of order 10 4 , which is in comparable to the constraint which has been indicated in [19].

We derive, compare, and discuss the constraints and evolution equations for the ww=-3/2 and w\

    A class of static and nonstatic solutions of the Brans-Dicke theory of gravitation is obtained in the presence of an electromagnetic field. The metric coefficients and fields (both scalar and electromagnetic) are supposed to be functions of any three independent variables. The major result of the paper may be stated as follows: ''Corresponding to any diagonalizable solution of Einstein's vacuum field equations in which fields and metric coefficients are functions of not more than three variables, we can generate a solution of the coupled Brans-Dicke Maxwell field equations with nonzero electromagnetic field.''

    The principle of coherent Dicke narrowing in a thin vapor cell, in which sub-Doppler spectral line shapes are observed under a normal irradiation for a λ/2 thickness, is generalized to two-photon spectroscopy. Only the sum of the two wave vectors must be normal to the cell, making the two-photon scheme highly versatile. A comparison is provided between the Dicke narrowing with copropagating fields, and the residual Doppler broadening occurring with counterpropagating geometries. The experimental feasibility is discussed on the basis of a first observation of a two-photon resonance in a 300-nm-thick Cs cell. Extension to the Raman situation is finally considered

    The energy flux emitted during the accretion of matter onto a wormhole in the Brans-Dicke theory has been calculated. This characteristic is compared with its values calculated previously for wormholes in general relativity and for a Schwarzschild black hole.

    Banded iron formations (BIFs) have long been considered marine chemical precipitates or, as more recently proposed, the result of episodic density flows. In this study, we examined the mineralogy, petrography and chemistry of the Dales Gorge BIF to evaluate the validity of these models. Microbands...... provenance. Nonetheless, when all the lithologies (i.e., source rocks, S and BIF macrobands) are evaluated together, continuous geochemical trends can be observed. This suggests that at least part of the precursor material of BIF macrobands was sourced from the same material that gave origin to the S...

    In the present study, we investigated concentrations and composition profiles of perfluoroalkyl substances (PFASs) in surface water from the Daling River in different seasons. The highest concentration of ΣPFASs (9540 ng L(-1)) and dominant homologues were found in surface water collected in summer. Perfluorobutanoic acid (PFBA), perfluorobutane sulfonate (PFBS), and perfluorooctanoic acid (PFOA) were the dominant PFASs in four seasons with a total contribution of over 90%. The discharge of two fluorine chemical industry parks was predicted to be the main contamination source of PFASs in the study area. The daily and annual mass flows were calculated according to data of detected PFAS concentrations and water discharge, and the annual mass loading of PFASs into the Bohai Sea from the Daling River reached to 461 kg year(-1). Hazard assessment indicated that concentrations of PFASs in study area had little risk to aquatic organisms and wildlife. However, the multiple health risk would be relatively high if the water was served as drinking water in the study area.

  19. Negotiating Transcendentalism, Escaping « Paradise » : Herman Melville’s Moby-Dick.

    Directory of Open Access Journals (Sweden)

    Ramón Espejo Romero

    2010-06-01

    Full Text Available By reviewing the critical literature on Melville and Transcendentalism and then undertaking a close reading of Moby-Dick (1851, this paper argues that the novel reflects, among other things, an ongoing debate between the novelist and Transcendentalist philosophy. While in later works, Melville seems to express a more robust condemnation of the Concord movement and its dangerous idealism, Moby-Dick occupies less firmly-defined territory. The Transcendentalist urge of an Ahab to be himself is a counterpoint to Ishmael’s more idiosyncratic deployment of self-reliance, communion with the oversoul, and various other concepts easy to trace back to Emerson or Thoreau. The conclusion seems to be that a negotiation is necessary if Transcendentalism is to be heeded at all, precisely the kind of negotiation Ishmael undertakes throughout the novel, one which spares him from the maelstrom created by a more radical approach to self-acceptance and self-fashioning.

  20. First-Order Quantum Phase Transition for Dicke Model Induced by Atom-Atom Interaction

    International Nuclear Information System (INIS)

    Zhao Xiu-Qin; Liu Ni; Liang Jiu-Qing

    2017-01-01

    In this article, we use the spin coherent state transformation and the ground state variational method to theoretically calculate the ground function. In order to consider the influence of the atom-atom interaction on the extended Dicke model’s ground state properties, the mean photon number, the scaled atomic population and the average ground energy are displayed. Using the self-consistent field theory to solve the atom-atom interaction, we discover the system undergoes a first-order quantum phase transition from the normal phase to the superradiant phase, but a famous Dicke-type second-order quantum phase transition without the atom-atom interaction. Meanwhile, the atom-atom interaction makes the phase transition point shift to the lower atom-photon collective coupling strength. (paper)

  1. Dynamics of cosmological perturbations in modified Brans-Dicke cosmology with matter-scalar field interaction

    Science.gov (United States)

    Kofinas, Georgios; Lima, Nelson A.

    2017-10-01

    In this work we focus on a novel completion of the well-known Brans-Dicke theory that introduces an interaction between the dark energy and dark matter sectors, known as complete Brans-Dicke (CBD) theory. We obtain viable cosmological accelerating solutions that fit supernovae observations with great precision without any scalar potential V (ϕ ). We use these solutions to explore the impact of the CBD theory on the large scale structure by studying the dynamics of its linear perturbations. We observe a growing behavior of the lensing potential Φ+ at late-times, while the growth rate is actually suppressed relatively to Λ CDM , which allows the CBD theory to provide a competitive fit to current RSD measurements of f σ8. However, we also observe that the theory exhibits a pathological change of sign in the effective gravitational constant concerning the perturbations on subhorizon scales that could pose a challenge to its validity.

    The field equations of Brans-Dicke gravity coupled to a mass-varying vector field are derived. Anisotropic cosmological solutions with a locally rotationally symmetric Bianchi type I metric and time-dependent scalar and electric vector fields are studied. A particular class of exact solutions for which all the variable parameters have a power-law time dependence is given. The universe expands with a constant expansion anisotropy within this class of solutions. We show that the accelerating ex...

    While looking for a nice, easy to perform and cheap students' project in 2009, we investigated X-band (8 to 12 GHz) microwave devices. A 5 m parabolic dish antenna and an X-band down-converter were already available, but we had no antenna feed in our tool box. A web search yielded a simple feed horn design and found sketches and descriptions by Dick Turrin (W2IMU) from 1991.

  6. Brans-Dicke Theory with Λ>0: Black Holes and Large Scale Structures.

    Science.gov (United States)

    Bhattacharya, Sourav; Dialektopoulos, Konstantinos F; Romano, Antonio Enea; Tomaras, Theodore N

    2015-10-30

    A step-by-step approach is followed to study cosmic structures in the context of Brans-Dicke theory with positive cosmological constant Λ and parameter ω. First, it is shown that regular stationary black-hole solutions not only have constant Brans-Dicke field ϕ, but can exist only for ω=∞, which forces the theory to coincide with the general relativity. Generalizations of the theory in order to evade this black-hole no-hair theorem are presented. It is also shown that in the absence of a stationary cosmological event horizon in the asymptotic region, a stationary black-hole horizon can support a nontrivial Brans-Dicke hair. Even more importantly, it is shown next that the presence of a stationary cosmological event horizon rules out any regular stationary solution, appropriate for the description of a star. Thus, to describe a star one has to assume that there is no such stationary horizon in the faraway asymptotic region. Under this implicit assumption generic spherical cosmic structures are studied perturbatively and it is shown that only for ω>0 or ω≲-5 their predicted maximum sizes are consistent with observations. We also point out how, many of the conclusions of this work differ qualitatively from the Λ=0 spacetimes.

  7. Regular Solutions in Vacuum Brans-Dicke Theory Compared to Vacuum Einstein Theory

    Directory of Open Access Journals (Sweden)

    Alina Khaybullina

    2013-01-01

    Full Text Available We will confront some static spherically symmetric vacuum Brans-Dicke solutions in the Jordan and Einstein Frames with the Robertson parameters. While the regular solution in the vacuum Einstein theory is just the Schwarzschild black hole, the same in the Jordan frame Brans-Dicke theory is shown to represent not a black hole but a traversable wormhole. But, in this case, the valid range of ω becomes too narrow to yield the observed weak field Robertson parameters at the positive mass mouth. The corresponding solution in the Einstein frame also provides a regular wormhole, and it yields the correct parametric values but only up to “one and half order.” We argue that a second-order contribution can in principle distinguish between the signatures of the regular wormhole and the singular Buchdahl solution in the Einstein frame. Thus, at the level of regular solutions, Brans-Dicke theory in each frame predicts effects very different from those of Einstein's theory. To our knowledge, these theoretical distinctions seem not to have received adequate attention so far.

    We investigate chameleonic Brans-Dicke model applied to the FRW universes. A framework to study stability and attractor solutions in the phase space is developed for the model. We show that depending on the matter field and stability conditions, it is possible to realize phantom-like behavior without introducing phantom filed in the model while the stability is fulfilled and phantom crossing occurs. The statefinder parameters to the model for different kinds of matter interacting with the chameleon scalar field are studied. We also compare our model with present day observations

    2011-04-01

    Gravitational wave observations can be used to probe non-linear gravitational interactions and thus provide strong tests of Einstein's theory of general relativity. Using the tools of numerical relativity, we present results from the late inspiral and merger of a binary black hole system in Jordan-Brans-Dicke-Fierz theory. In particular, we address whether in this theory the gravitational waves produced during the coalescence differ from those from general relativity. We discuss how future gravitational wave observations of binary black hole mergers could be used to place bounds on such scalar-tensor theories.

    It has been shown earlier that, for a perfect fluid, a perfect gas law of state, and the Robertson-Walker metric, an exponential phase in Brans-Dicke cosmology is possible, with both positive pressure and density, but not with the violated energy condition p = -ρ. We demonstrate in this paper that the inclusion of a cosmological constant into the theory does not change that picture.

    1988-01-01

    Using dynamical system theory we investigate homogeneous and isotropic models in Brans-Dicke theory for perfect fluids with general equation of state and arbitrary ω. Phase diagrams are drawn on the Poincare sphere which permits a qualitative analysis of the models. Based on this analysis we construct a method for generating classes of solutions in Brans-Dicke theory. The same technique is used for studying models arising from non-minimal coupling of electromagnetism with gravity. In addition, viscous fluids are considered and non-singular solutions with bulk viscosity are found. (author)

    We study inflation in the Brans-Dicke gravity as a special model of the scalar-tensor gravity. We obtain the inflationary observables containing the scalar spectral index, the tensor-to-scalar ratio, the running of the scalar spectral index and the equilateral non-Gaussianity parameter in terms of the general form of the potential in the Jordan frame. Then, we compare the results for various inflationary potentials in light of the Planck 2015 data. Our study shows that in the Brans-Dicke gravity, the power-law, inverse power-law and exponential potentials are ruled out by the Planck 2015 data. But, the hilltop, Higgs, Coleman-Weinberg and natural potentials can be compatible with Planck 2015 TT,TE,EE+lowP data at 95% CL. Moreover, the D-brane, SB SUSY and displaced quadratic potentials can be in well agreement with the observational data since their results can lie inside the 68% CL region of Planck 2015 TT,TE,EE+lowP data.

  13. Stellar explosion in the weak field approximation of the Brans-Dicke theory

    We treat a very crude model of an exploding star, in the weak field approximation of the Brans-Dicke theory, in a scenario that resembles some characteristic data of a type Ia supernova. The most noticeable feature, in the electromagnetic component, is the relationship between the absolute magnitude at maximum brightness of the star and the decline rate in one magnitude from that maximum. This characteristic has become one of the most accurate methods to measure luminosity distances to objects at cosmological distances (Phillips M M 1993 Astrophys. J. 413 L105; see www.all-science-fair-projects.com/ science{sub f}air{sub p}rojects{sub e}ncyclopedia/Supernova, for a brief description of supernovae types). An interesting result is that the active mass associated with the scalar field is totally radiated to infinity, representing a mass loss in the ratio of the 'tensor' component to the scalar component of 1 to (2{omega} + 3) ({omega} is the Brans-Dicke parameter), in agreement with a general result of Hawking (1972 Commun. Math. Phys. 25 167). Then, this model shows explicitly, in a dynamical case, the mechanism of the radiation of a scalar field, which is necessary to understand the Hawking result.

  14. Robert Dicke and the naissance of experimental gravity physics, 1957-1967

    Science.gov (United States)

    Peebles, Phillip James Edwin

    2017-06-01

    The experimental study of gravity became much more active in the late 1950s, a change pronounced enough be termed the birth, or naissance, of experimental gravity physics. I present a review of developments in this subject since 1915, through the broad range of new approaches that commenced in the late 1950s, and up to the transition of experimental gravity physics to what might be termed a normal and accepted part of physical science in the late 1960s. This review shows the importance of advances in technology, here as in all branches of natural science. The role of contingency is illustrated by Robert Dicke's decision in the mid-1950s to change directions in mid-career, to lead a research group dedicated to the experimental study of gravity. The review also shows the power of nonempirical evidence. Some in the 1950s felt that general relativity theory is so logically sound as to be scarcely worth the testing. But Dicke and others argued that a poorly tested theory is only that, and that other nonempirical arguments, based on Mach's Principle and Dirac's Large Numbers hypothesis, suggested it would be worth looking for a better theory of gravity. I conclude by offering lessons from this history, some peculiar to the study of gravity physics during the naissance, some of more general relevance. The central lesson, which is familiar but not always well advertised, is that physical theories can be empirically established, sometimes with surprising results.

  15. Notes on the post-Newtonian limit of the massive Brans-Dicke theory

    International Nuclear Information System (INIS)

    Roshan, Mahmood; Shojai, Fatimah

    2011-01-01

    We consider the post-Newtonian limit of the massive Brans-Dicke theory and make some notes about the post-Newtonian limit of the case ω = 0. This case is dynamically equivalent to the metric f(R) theory. It is known that this theory can be compatible with the solar system tests if the Chameleon mechanism occurs. Also, it is known that this mechanism is because of the nonlinearity in the field equations produced by the largeness of the local curvature relative to the background curvature. Thus, the linearization of the field equations breaks down. On the other hand, we know that the Chameleon mechanism exists when a coupling between the matter and the scalar field exists. In the Jordan frame of the Brans-Dicke theory, we have no such coupling. But in the Einstein frame, this theory behaves like a Chameleon scalar field. By confining ourselves to the case ω = 0, we show that 'Chameleon-like' behaviour can exist also in the Jordan frame, but it has an important difference compared with the Chameleon mechanism. Also we show that the conditions which lead to the existence of a 'Chameleon-like' mechanism are consistent with the conditions in the post-Newtonian limit which correspond to a heavy scalar field at the cosmological scale and a small effective cosmological constant. Thus, one can linearize field equations to the post-Newtonian order, and this linearization has no contradiction with the existence of 'Chameleon-like' behaviour.

  16. Acoustics and its relation to language: The influence of Dick Bolt

    Science.gov (United States)

    Stevens, Kenneth N.

    2003-04-01

    Under the mentoring of Dick Bolt, and the stimulation he provided in the Acoustics Laboratory at MIT, many students were exposed to a range of topics in acoustics, including mechanisms of sound generation, radiation, and propagation, noise control, acoustics of resonators and rooms, human responses to sound, and speech perception under various adverse conditions. As someone who became interested in speech communication, I have recognized that this kind of quantitative background in acoustics is an important requirement for developing models of how humans produce speech, how they perceive and understand speech, and how children acquire these skills. Speech production involves sound sources produced by a nonlinear mechanical system and by noise arising from turbulent airflow. Sound is propagated in a vocal tract with yielding walls, and acoustic coupling is introduced by lossy resonators attached to the vocal tract, including the trachea and the nasal cavity. These acoustic principles of sound generation create an inventory of sound types that give rise to distinctive responses in the ears and brains of listeners. The solid grounding in acoustics provided by Dick Bolt and his leadership have helped in the formation of this linkage between acoustics, speech physiology, linguistics, and human perception.

    2015-01-01

    Many countries are rolling out smart electricity meters. These measure a home's total power demand. However, research into consumer behaviour suggests that consumers are best able to improve their energy efficiency when provided with itemised, appliance-by-appliance consumption information. Energy disaggregation is a computational technique for estimating appliance-by-appliance energy consumption from a whole-house meter signal. To conduct research on disaggregation algorithms, researchers require data describing not just the aggregate demand per building but also the 'ground truth' demand of individual appliances. In this context, we present UK-DALE: an open-access dataset from the UK recording Domestic Appliance-Level Electricity at a sample rate of 16 kHz for the whole-house and at 1/6 Hz for individual appliances. This is the first open access UK dataset at this temporal resolution. We recorded from five houses, one of which was recorded for 655 days, the longest duration we are aware of for any energy dataset at this sample rate. We also describe the low-cost, open-source, wireless system we built for collecting our dataset.

  18. Science Fiction and the Risks of the Anthropocene: Anticipated Transformations in Dale Pendell’s The Great Bay

    Directory of Open Access Journals (Sweden)

    Weik von Mossner, Alexa

    2014-11-01

    Full Text Available Covering the time span from 2021 to 16000 N.C., Dale Pendell’s speculative novel The Great Bay chronicles the profound climatic, geological and ecological transformations that California undergoes during these fourteen millennia. Human life becomes unimaginably small on such a time scale, and Pendell responds to that representational challenge by compiling a wide variety of texts that zero in on individual humans at different points in the future rather than offering a continuous story or central character. In a way, that place is taken by the geographical region that is the focus of the narrative and gives the book its title. Timothy Morton has argued that because we live in the Anthropocene we can no longer understand history as exclusively human. Pendell’s “Chronicle of the Collapse” suggests that the same is true for storytelling, offering readers the story of a nonhuman protagonist that changes slowly over time. The result is a highly fragmented narrative that is interesting for what it tries to achieve but at the same time remarkably unengaging. In its distant and distanced rendering of future ecological change and human anguish, The Great Bay is a grave reminder not only of the incalculable risks of the Anthropocene, but also of the basic tenets of realist storytelling.

    This study aimed to provide basic data on the composition of metallic elements, including toxicologically important Cd and Hg, in popular and prized wild King Bolete mushrooms. We investigated the importance of soil substratum as a source of these metals. ICP-OES and CV-AAS were applied to determine the profile of Al, Ba, Ca, Cd, Cu, Fe, Hg, K, Mg, Mn, Na, Sr and Zn in caps and stipes of King Bolete mushroom and in the surface layer of soil (0-10 cm) from the Płocka Dale area of Poland. Hg, Cu, Cd, Zn, Mg and K exhibited bioconcentration factors (BCF) > 1. Specifically, Hg, Cu and Cd (mean BCFs for caps were 110, 19 and 16, respectively) were efficiently bioconcentrated by King Bolete, while other elements were bioexcluded (BCF < 1). Cadmium was present in the caps at mean levels of 5.5 ± 2.4 mg kg(-1) dry weight (dw) and mercury at levels of 4.9 ± 1.4 mg kg(-1) dw, both occurring at elevated concentrations in those King Bolete mushrooms surveyed.

    Full Text Available The aim of this essay is to discuss the legacy of the roman noir in contemporary detective fiction produced outside the hegemonic center of power, here represented by the novel Death in Little Tokyo (1996, written by Japanese-American author Dale Furutani. Starting from the concept of the metaphysical detective (Haycraft 76; Holquist 153-156, characterized by deep questioning about narrative, interpretation, subjectivity, the nature of reality and the limits of knowledge, this article proposes a discussion about how these literary works, which at first sight represent a traditionally Anglo-American genre, constitute narratives that aim to rescue the memory, history and culture of marginalized communities. Typical of late modernity detective fiction, the metaphysical detective has none of the positivistic detective’s certainties, as he does not share in his Cartesian notion of totality, being presented instead as a successor of the hardboiled detective of the roman noir. In this article I intend to analyze the paths chosen by the author and discuss how his re-reading of the roman noir dialogues with the texts of hegemonic noire detective fiction, inscribing them in literary tradition and subverting them at the same time.

    We explore a 5D Brans-Dicke scalar cosmology by conjecturing that the four-dimensional Hubble parameter varies as H = inphis, in in ℝ and s is some unknown power index and that the extra-dimensions compactify as the visible dimensions expand as b(t) ≈ ax(t), x in ℝ-. We mainly discuss the case x = -1. For critical values of in close to unity, it was observed that the acceleration of the universe occurs at red-shift close to z = 0.8 which indicates that in our model, accelerated expansion of the universe began only recently. Several interesting points are revealed and discussed in some detail.

  4. High-order corrections on the laser cooling limit in the Lamb-Dicke regime.

    Yi, Zhen; Gu, Wen-Ju

    2017-01-23

    We investigate corrections on the cooling limit of high-order Lamb-Dicke (LD) parameters in the double electromagnetically induced transparency (EIT) cooling scheme. Via utilizing quantum interferences, the single-phonon heating mechanism vanishes and the system evolves to a double dark state, from which we will obtain the mechanical occupation on the single-phonon excitation state. In addition, the further correction induced by two-phonon heating transitions is included to achieve a more accurate cooling limit. There exist two pathways of two-phonon heating transitions: direct two-phonon excitation from the dark state and further excitation from the single-phonon excited state. By adding up these two parts of correction, the obtained analytical predictions show a well consistence with numerical results. Moreover, we find that the two pathways can destructively interfere with each other, leading to the elimination of two-phonon heating transitions and achieving a lower cooling limit.

    The quantum dynamics of initial coherent states is studied in the Dicke model and correlated with the dynamics, regular or chaotic, of their classical limit. Analytical expressions for the survival probability, i.e. the probability of finding the system in its initial state at time t, are provided in the regular regions of the model. The results for regular regimes are compared with those of the chaotic ones. It is found that initial coherent states in regular regions have a much longer equilibration time than those located in chaotic regions. The properties of the distributions for the initial coherent states in the Hamiltonian eigenbasis are also studied. It is found that for regular states the components with no negligible contribution are organized in sequences of energy levels distributed according to Gaussian functions. In the case of chaotic coherent states, the energy components do not have a simple structure and the number of participating energy levels is larger than in the regular cases.

    The strong coupling regime is essential for efficient transfer of excitations between states in different quantum systems on timescales shorter than their lifetimes. The coupling of single spins to microwave photons is very weak but can be enhanced by increasing the local density of states by reducing the magnetic mode volume of the cavity. In practice, it is difficult to achieve both small cavity mode volume and low cavity decay rate, so superconducting metals are often employed at cryogenic temperatures. For an ensembles of N spins, the spin-photon coupling can be enhanced by √{N } through collective spin excitations known as Dicke states. For sufficiently large N the collective spin-photon coupling can exceed both the spin decoherence and cavity decay rates, making the strong-coupling regime accessible. Here we demonstrate strong coupling and cavity quantum electrodynamics in a solid-state system at room-temperature. We generate an inverted spin-ensemble with N 1015 by photo-exciting pentacene molecules into spin-triplet states with spin dephasing time T2* 3 μs. When coupled to a 1.45 GHz TE01δ mode supported by a high Purcell factor strontium titanate dielectric cavity (Vm 0.25 cm3, Q 8,500), we observe Rabi oscillations in the microwave emission from collective Dicke states and a 1.8 MHz normal-mode splitting of the resultant collective spin-photon polariton. We also observe a cavity protection effect at the onset of the strong-coupling regime which decreases the polariton decay rate as the collective coupling increases.

    Full Text Available Resumo: Nosso objetivo neste artigo consiste em analisar o espaço do absurdo no romance Caieira, do escritor matogrossense Ricardo Guilherme Dicke. Como suporte teóricometodológico, utilizamos as ideias sobre o absurdo de Camus. Durante a análise, percebemos que o espaço em que se desenvolvem as ações narradas em Caieira representa uma relação de dominação, em que os personagens são reduzidas a fantasmas ou objetos, presas num mundo de cal, árido de humanidade. Mesmo quando o personagem principal tenta reverter o quadro, acaba se transformando num reverso da mesma moeda, repetindo o modelo de dominação contra o qual se insurge, reeditando um ciclo de poder e dominação. Palavras-chave: Literatura brasileira; análise literária; absurdo; espaço.Abstract: Our aim in this paper is to analyze the space of the absurd at the novel Caieira, by Ricardo Guilherme Dicke, writer from Mato Grosso. As a theoretical-methodological support, we use the ideas of on the absurd presented by Camus. During the analysis, we find that the space in which the actions narrated in Caieira develop represents a relationship of domination, in which the characters are reduced to objects or ghosts, trapped in a world of lime, arid of humanity. Even when the main character tries to reverse the situation, eventually becoming a reverse of the same coin, repeating the pattern of domination against which it protests, reissuing a cycle of power and domination.

    Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are extremely persistent in the environment, and have the potential for long-range transport. The present study focused on the Daling River and its tributary, a larger river flowing into Liaodong Bay of the Bohai Sea. Recent studies have shown the elevated levels of PFOS and PFOA in the Daling River. Hence, the objective of this study was to investigate the seasonal changes, fate and transport modeling of PFOS and PFOA concentrations using one-dimensional DHI MIKE-11 river model. We designed three scenarios to assess the risk of PFOS and PFOA in surface water: the measured concentrations, constant maximum and the magnitude of a continuous constant load. The mean absolute errors divided by the mean of measured concentrations were 41-64% for PFOS and 29-36% for PFOA. The result indicated that PFOS and PFOA in the downstream of the Daling River would not reach a harmful level with the current load. The fluorochemical parks contributed an average of 44.57% of the total PFOS and 95.44% of the total PFOA flow that reached the estuary. The mass flow was observed as 1.74 kg y -1 for PFOS and 40.57 kg y -1 for PFOA to the Bohai Sea. These modeling results may be useful for monitoring the status and trends of emerging POPs and will help the determination of the risk to both humans and wildlife, in the estuarine and coastal areas of the Bohai Sea, China.

    On studying some new models of Robertson-Walker universes with a Brans-Dicke scalar field, it is found that most of these universes contain a dark energy like fluid which confirms the present scenario of the expansion of the universe. In one of the cases, the exact solution of the field equations gives a universe with a false vacuum, while in another it reduces to that of dust distribution in the Brans-Dicke cosmology when the cosmological constant is not in the picture. In one particular model it is found that the universe may undergo a Big Rip in the future, and thus it will be very interesting to investigate such models further. (paper)

    In the microwave 199Hg+ trapped-ion clock, the frequency instability degradation caused by the Dick effect is unavoidable because of the periodical interrogating field. In this paper, the general expression of the sensitivity function g(t) to the frequency fluctuation of the interrogating field with Nπ-pulse (N is odd) is derived. According to the measured phase noise of the 40.5-GHz microwave synthesizer, the Dick-effect limited Allan deviation of our 199Hg+ trapped-ion clock is worked out. The results indicate that the limited Allan deviations are about and respectively in the linear ion trap and in the two-segment extended linear ion trap under our present experimental parameters.

    A new Dicke-type maser model is proposed. It involves infinite (in the thermodynamic limit) modes and A 2 -term. The approximating Hamiltonian method (AHM) is shown to be valid for the exact calculation of the free energy per portible and some thermodynamic averagos for this model in the thermodynamic limit. The model persists in a superradiant phase transition at least for the rotating-wave approximation in the interaction

    Motivated by the work of Yang et al. (Mod. Phys. Lett.

We have studied the correspondence between the quintessence, the DBI-essence, and the tachyon scalar-field models with the NHDE model in the framework of chameleon Brans-Dicke cosmology. Deriving an expression of the Hubble parameter H and, accordingly, ρ{sub D} in the context of chameleon Brans-Dicke chameleon cosmology, we have reconstructed the potentials and dynamics for these scalar-field models. Furthermore, we have examined the stability for the obtained solutions of the crossing of the phantom divide under a quantum correction of massless conformally invariant fields, and we have seen that the quantum correction could be small when the phantom crossing occurs and the obtained solutions of the phantom crossing could be stable under the quantum correction. It has also been noted that the potential increases as the matter. chameleon coupling gets stronger with the evolution of the universe. (orig.)

  14. The Brans-Dicke gravity as a theory of dark matter

    International Nuclear Information System (INIS)

    Kim, Hongsu

    2010-01-01

    The pure Brans-Dicke (BD) gravity with or without the cosmological constant Λ has been taken as a model theory for dark matter. Indeed, there has been a consensus that unless one modifies either the standard theory of gravity, namely, general relativity, or the standard model for particle physics, or both, one can never achieve a satisfying understanding of the phenomena associated with dark matter and dark energy. Along this line, our dark matter model in this work can be thought of as an attempt to modify the gravity side alone in the simplest fashion to achieve the goal. Among others, it is demonstrated that our model theory can successfully predict the emergence of a dark matter halo-like configuration in terms of a self-gravitating spacetime solution to the BD field equations and reproduce the flattened rotation curve in this dark halo-like object in terms of the non-trivial energy density of the BD scalar field, which was absent in the context of general relativity, where Newton's constant is strictly a 'constant' having no dynamics. Our model theory, however, is not entirely without flaw, such as the prediction of relativistic jets in all types of galaxies, which actually is not the case.

    We study the collapse process of a homogeneous perfect fluid (in FLRW background) with a barotropic equation of state in Brans–Dicke (BD) theory in the presence of phase space deformation effects. Such a deformation is introduced as a particular type of non-commutativity between phase space coordinates. For the commutative case, it has been shown in the literature (Scheel, 1995), that the dust collapse in BD theory leads to the formation of a spacetime singularity which is covered by an event horizon. In comparison to general relativity (GR), the authors concluded that the final state of black holes in BD theory is identical to the GR case but differs from GR during the dynamical evolution of the collapse process. However, the presence of non-commutative effects influences the dynamics of the collapse scenario and consequently a non-singular evolution is developed in the sense that a bounce emerges at a minimum radius, after which an expanding phase begins. Such a behavior is observed for positive values of the BD coupling parameter. For large positive values of the BD coupling parameter, when non-commutative effects are present, the dynamics of collapse process differs from the GR case. Finally, we show that for negative values of the BD coupling parameter, the singularity is replaced by an oscillatory bounce occurring at a finite time, with the frequency of oscillation and amplitude being damped at late times.

  16. Quantum phase transitions of light in a dissipative Dicke-Bose-Hubbard model

    The impact that the environment has on the quantum phase transition of light in the Dicke-Bose-Hubbard model is investigated. Based on the quasibosonic approach, mean-field theory, and perturbation theory, the formulation of the Hamiltonian, the eigenenergies, and the superfluid order parameter are obtained analytically. Compared with the ideal cases, the order parameter of the system evolves with time as the photons naturally decay in their environment. When the system starts with the superfluid state, the dissipation makes the photons more likely to localize, and a greater hopping energy of photons is required to restore the long-range phase coherence of the localized state of the system. Furthermore, the Mott lobes depend crucially on the numbers of atoms and photons (which disappear) of each site, and the system tends to be classical with the number of atoms increasing; however, the atomic number is far lower than that expected under ideal circumstances. As there is an inevitable interaction between the coupled-cavity array and its surrounding environment in the actual experiments, the system is intrinsically dissipative. The results obtained here provide a more realistic image for characterizing the dissipative nature of quantum phase transitions in lossy platforms, which will offer valuable insight into quantum simulation of a dissipative system and which are helpful in guiding experimentalists in open quantum systems.

  19. Eternal extended inflation and graceful exit from old inflation without Jordan-Brans-Dicke

    1990-10-01

    Recently a possible solution to the graceful exit problem of the old inflation was proposed in the context of the Jordan-Brans-Dicke theory (extended inflation). In this paper we will argue that inflation in this theory occurs in a most natural way if it starts near the Planck density, as in the standard version of chaotic inflation. With most natural initial conditions, the inflationary universe in the JBD theory enters the stage of permanent reproduction of new inflationary domains (eternal extended inflation). In order to realize the extended inflation scenario at least two classical scalar fields driving inflation are necessary, as distinct from the simplest versions of new and chaotic inflation. It is shown that in the theory of two scalar fields one can solve the graceful exit problem even without modifying the Einstein gravity theory, due to the possibility that the decay rate of the false rate vacuum in old inflation depends on the value of the second scalar field and hence on time.

    Full Text Available Julie Holledge, panel chairperson and member of the International Ibsen Committee, invited myself along with 3 others to participate in the Inaugural Artists’ Keynote Panel: Applied Ibsen on Four Continents: The Artists’ Intentions. My presentation focused on “The Former Miss Barstow with every Tom, Dick and Harry in a doll’s house.” This was an adaptation of Ibsen’s “A Doll’s House” produced and staged in Los Angeles, California, 1987.  For the XIIIth International Ibsen Conference at the University of Tromsø, Norway, I projected images; a few found on the internet, and many from the production itself, as well as a video clip shown streaming live from YouTube. The article describes the social context of the 80s, analyzes the reinterpretation of Ibsen’s characters, and sets out to explain the symbology of the sets and costumes. I also touch on the differences between this production and Ibsen’s original in four important aspects. These would be the macaroons, the Tarantella, the silk stockings and the end of the play. Finally, I explain my decision to upload this version of “A Doll’s House,’ scene by scene, to my page on YouTube. Having shown films and videos for many years at festivals around the globe, I was looking for a way to step outside that box and reach an international audience just beyond my keyboard. In all of these ways, the goal has been to illuminate the ways in which an artist takes Ibsen’s text and applies it to the specific social context of their time and culture.

    Observation shows that the velocities of stars grow by approximately 2-3 orders of magnitude when the distances from the centers of the galaxies are in the range of 0.5-82.3 kpc, before they begin to tend to a constant value. Up to now, the reason for this behavior is still a matter for debate. In this work, we propose a model which adequately describes this unusual behavior using a (nearly) cylindrical symmetrical solution in the framework of a scalar-tensor-like (the Brans-Dicke model) theory of gravity.

    Within the framework of the scalar-tensor models of gravitation and by relying on analytical and numerical techniques, we establish the existence of a class of spherically symmetric spacetimes containing a naked singularity. Our result relies on and extends a work by Christodoulou on the existence of naked singularities for the Einstein-scalar field equations. We establish that a key parameter in Christodoulou's construction couples to the Brans-Dicke field and becomes a dynamical variable, which enlarges and modifies the phase space of solutions. We recover analytically many properties first identified by Christodoulou, in particular the loss of regularity (especially at the center), and then investigate numerically the properties of these spacetimes.

  4. Influence of counter-rotating interaction on quantum phase transition in Dicke-Hubbard lattice: an extended coherent-state approach

    2016-10-01

    We investigate the ground-state behavior of the Dicke-Hubbard model including counter-rotating terms. By generalizing an extended coherent-state approach within mean-field theory, we self-consistently obtain the ground-state energy and delocalized order parameter. Localization-delocalization quantum phase transition of photons is clearly observed by breaking the parity symmetry. Particularly, Mott lobes are fully suppressed, and the delocalized order parameter shows monotonic enhancement by increasing qubit-cavity coupling strength, in sharp contrast to the Dicke-Hubbard model under rotating-wave approximation. Moreover, the corresponding phase boundaries are stabilized by decreasing photon hopping strength, compared to the Rabi-Hubbard model.

  5. Testing Timescales for Rhythms Recorded in the 2.5 Ga Banded Iron Formation of the Dales Gorge Member (Brockman Iron Formation, Hamersley Group, Australia)

    The classic, Superior-type banded iron formation (BIF) of the Precambrian Dales Gorge Member (DGM) of the Brockman Iron Formation, Hamersley Basin, Western Australia consists of a succession of micro- (millimeter-scale) and meso- (centimeter to decimeter-scale) bands of primarily iron-silica chemical sediment alternations, separated into macro- (meter to decameter-scale) bands by shales (1). Here, we present a time-frequency analysis of a gray-scale scan of the DGM "type section core" Hole 47A with small contributions from Hole EC10 (1) to provide a comprehensive characterization of banding patterns and periodicity throughout the 140 m section. SHRIMP zircon ages (2) indicate that the DGM was deposited over approximately 30 myr during the Archean-Proterozoic transition just prior to the Great Oxidation Event. This suggests that the banding patterns recorded Milankovitch cycles, although with orbital-rotational parameters significantly different from present-day due to Earth's tidal dissipation and chaotic episodes in the Solar System since 2.5 Ga. Banding patterns change systematically within the formation in response to slowly varying environmental conditions, which have been interpreted previously to be related to sea level change and basin evolution (3). Researchers, including (2), have questioned the 30 myr duration, suggesting instead that the micro-bands may be annual in scale. This would indicate a much shorter duration of less than 150 kyr for the DGM. In an attempt to determine whether Milankovitch cycles could have generated the meso-band patterns, we present detailed studies of BIF0 and BIF12, which typify the marked changes in meso-banding along the section. Objective procedures are also applied, including ASM (4) and TIMEOPT (5) to test for a range of potential alternative timescales assuming orbital-rotational parameter values modeled for 2.5 Ga.

Les molécules solubilisées dans l'alcane sont appelées maltènes et peuvent à leur tour être fractionnées par chromatographie en phase liquide; on obtient alors trois nouvelles fractions appelées résines, aromatiques et saturées. La plupart des travaux de recherche réalisés sur ces molécules complexes concernent la détermination de la composition chimique obtenue à l'aide de diverses techniques d'analyse telles la spectroscopie infrarouge et la résonance magnétique nucléaire. En revanche, peu d'informations sur la macrostructure colloïdale des asphaltènes sont disponibles dans la littérature. La détermination de la masse moléculaire a été le premier objectif : plusieurs méthodes, comme l'osmométrie à tension de vapeur, ont été appliquées. La conclusion principale de ces déterminations est la grande

    Full Text Available This article aims to analyze the environmental significance of Moby Dick, narrative that, in the mid-nineteenth century, warned, indirectly, on the need to preserve nature against the excesses of whaling. For this, we analyzed the main regulations that composes the environmental protection regime for whaling marine life, one of which allowed exceptions to the prohibition of hunting, based both on alleged scientific research needs as the claim of cultural practices, and the decision of the ICJ in the case brought by Australia in face of Japan.

  11. An aeolian component in Pleistocene and Holocene valley aggradation: evidence from Dicks Creek catchment, Yass, New South Wales

    International Nuclear Information System (INIS)

    Melis, M.I.; Acworth, R.I.

    2001-01-01

    Four late Quaternary depositional units are identified overlying sub-vertically dipping Ordovician bedrock in the upper reaches of the Dicks Creek catchment, near Yass in the Southern Highlands of New South Wales. The units are spatially discontinuous and separated from each other by erosional unconformities. They are found only on the lower slopes and in the valley floors, often exposed by recent gully erosion. The oldest unit (Unit 4) is a competent consolidated well-sorted fine to medium silt that unconformably overlies bedrock. It often forms the base to erosion gullies. Unit 3 is strongly dispersible and frequently has the characteristics of a debris flow. Unit 3 is particularly prone to sheet erosion and exhibits a high risk of dryland salinity development. Unit 2 is light to dark grey, poorly sorted and often contains irregularly dispersed charcoal. Unit 2 is unconformably overlain by a predominantly pale yellow sand (Unit 1) that shows clear evidence of very recent deposition. Physical and chemical characteristics of Units 2, 3, and 4 suggest an aeolian component. The silt size (4-8 on phi scale) fraction of Unit 4 is often >70% of the total mass, with grain sizes consistent with an origin as aeolian dust. Unit 3 is yellow brown in colour and often has the characteristics of a diamict with a major grain size component similar in size to Unit 4. Unit 2 is typically uniform in appearance and contains a predominantly kaolinite and illite clay mineralogy that contrasts strongly with a predominance of quartz in the underlying bedrock. A simple sediment budget indicates that the volume of Unit 2 could be accounted for by a combination of sheet and rill erosion within the catchment and additional aeolian deposition in the order of 4-8 t/km 2 year. Radiocarbon dates for charcoal recovered from Unit 2 indicate that some deposition was associated with cooler, drier conditions of the late Holocene 'Little Ice Age', approximately 200-600 years ago.

    2011-03-01

    Horace Richard Crane (1907-2007) was born and educated in California. His childhood was full of activities that helped him become an outstanding experimental physicist. As a graduate student at the California Institute of Technology (1930-1934), he had the good fortune to work with Charles C. Lauritsen (1892-1968) just as he introduced accelerator-based nuclear physics to Caltech. They shared the euphoric excitement of opening up a new field with simple, ingenious apparatus and experiments. This work prepared Crane for his career at the University of Michigan (1935-1973) where in the 1950s, after making the first measurement of the electron's magnetic moment, he devised the g-2 technique and made the first measurement of the anomaly in the electron's magnetic moment. A man of direct, almost laconic style, he made lasting contributions to the exposition of physics to the general public and to its teaching in high schools, community colleges, four-year colleges, and universities. I tell how he became a physicist and describe some of his early achievements.

  14. Reduction of Systematic Errors in Diagnostic Receivers Through the Use of Balanced Dicke-Switching and Y-Factor Noise Calibrations

    Energy Technology Data Exchange (ETDEWEB)

    John Musson, Trent Allison, Roger Flood, Jianxun Yan

    2009-05-01

    Receivers designed for diagnostic applications range from those having moderate sensitivity to those possessing large dynamic range. Digital receivers have a dynamic range which are a function of the number of bits represented by the ADC and subsequent processing. If some of this range is sacrificed for extreme sensitivity, noise power can then be used to perform two-point load calibrations. Since load temperatures can be precisely determined, the receiver can be quickly and accurately characterized; minute changes in system gain can then be detected, and systematic errors corrected. In addition, using receiver pairs in a balanced approach to measuring X+, X-, Y+, Y-, reduces systematic offset errors from non-identical system gains, and changes in system performance. This paper describes and demonstrates a balanced BPM-style diagnostic receiver, employing Dicke-switching to establish and maintain real-time system calibration. Benefits of such a receiver include wide bandwidth, solid absolute accuracy, improved position accuracy, and phase-sensitive measurements. System description, static and dynamic modelling, and measurement data are presented.

  15. Dicke narrowing of the polarized Stokes--Raman Q branch of the v=0→1 transition of D2 in He

    International Nuclear Information System (INIS)

    Ab initio calculations were carried out for several Stokes--Raman Q branch line shapes of the v=0→1 transition of D 2 in helium in the low pressure regime where Dicke narrowing is observed. Five different approximations were studied: a generalization of Hess's method, which is based on the equivalent of a Bhatnagar--Gross--Krook model of the Waldmann--Snider kinetic equation; two high pressure asymptotes of Hess's method; a moment method of the Chapman--Cowling type due to Corey and McCourt; and a collision kernel method that has found extensive use lately in rarefied gas dynamics and other highly nonequilibrium states. Using generalized cross sections incorporating S-matrices calculated in the close coupled approximation with an ab initio potential energy surface, most of the methods agreed moderately well with the most recent line width determinations at most densities. Of the five methods, the generalized Hess and collision kernel methods agreed best with experiment over the whole range. At the lowest densities where the collision kernel method might be expected to have convergence problems none were observed, and at high densities the ab initio generalized Hess method may not be flexible enough

    Full Text Available Nowadays many universities in the world apply technology enhanced learning in order to help learning activities. Due to the potentials technology enhanced learning offers, recent education using it and universities in particular are trying to apply it. One of the subjects of this research is The Accounting Department of Airlangga University in Surabaya. The idea of this research is to investigate the students about how they know deeply about e-learning system and learning objectives as a first step to conduct e-learning model. After the model completed, the next step is to prepare database learning. Entity Relationship Diagram (ERD can help to explain the model. The purpose of this research was done by using Dick and Carey Design Model. There are nine steps to conduct e-learning model. All steps can be categorized into three steps research: first is the introduction or empirical study, the next step is the design and the last is the feedback after the implementation. The methodology used in this research is using Qualitative Exploratory, by using questionnaire and interviews as data collection techniques. The analysis of the data shows organization requires information about e-learning content, user as a learning subject and information technology infrastructures. E-learning model as one of the alternative learning can help users to optimized learning.

  17. Parallel editing, multi-positionality and maximalism – cosmopolitan effects as explored in some art works by Melanie Jackson and Vivienne Dick

    Full Text Available Garfield produces a critique of minimalist art practice by demonstrating how the artist Melanie Jackson’s Some things you are not allowed to send around the world (2003 and 2006 and the experimental film-maker Vivienne Dick’s Liberty’s booty (1980 – neither of which can be said to be about feeling ‘at home’ in the world, be it as a resident or as a nomad – examine global humanity through multi-positionality, excess and contingency, and thereby begin to articulate a new cosmopolitan relationship with the local – or, rather, with many different localities – in one and the same maximalist sweep of the work. ‘Maximalism’ in Garfield’s coinage signifies an excessive overloading (through editing, collage, and the sheer density of the range of the material that enables the viewer to insert themselves into the narrative of the work. In the art of both Jackson and Dick Garfield detects a refusal to know or to judge the world; instead, there is an attempt to incorporate the complexities of its full range into the singular vision of the work, challenging the viewer to identify what is at stake.

It is argued that the solution could be a wormhole analogue of the Horowitz-Ross naked black hole. It is further demonstrated that the wormhole is traversible only "in principle", but not in practice. Using a recently proposed measure of total gravitational energy inside a static wormhole configuration, it is shown that the wormhole contains repulsive gravity required for the defocussing ...

    This part of ISO 11140 specifies the performance of the indicator system in combination with the test load with which it is intended to be used. The test load may be presented with the indicator system already incorporated and intended for single use, or it may be intended for multiple use with a new indicator system to be inserted prior to each use. The indicator for which the performance is specified in this part of ISO 11140 is intended to indicate when steam penetration has been inadequate. The performance of the indicator specified in this part of ISO 11140 should be equivalent, but not necessarily identical, to the performance obtained in the Bowie and Dick-type test as described in ISO 11140-3. Equivalence should be regarded as providing a similar response to steam penetration with any differences being predictable and such that the necessary level of assurance of satisfactory steam penetration is provided. An indicator meeting this specification is not intended to identify which of the potential causes of poor steam penetration was responsible for the failure indicated by the test. This part of ISO 11140 specifies the performance for a Class 2 indicator to be used as an alternative to the Bowie and Dick-type test for steam sterilizers for wrapped health care goods (instruments, etc., and porous loads). The Bowie and Dick-type test is used for routine testing of steam sterilizers and validation of steam sterilization processes. An indicator complying with this part of ISO 11140 incorporates a specified material which is used as a test load. This test load may, or may not, be re-usable. This part of ISO 11140 does not specify requirements for the test load, but specifies the performance of the indicator in combination with the test load with which it is intended to be used. The indicator specified in this part of ISO 11140 is intended to identify poor steam penetration but does not necessarily indicate the cause of this poor steam penetration. This part of

    The British Cave Research Association (BCRA) is the research division of the British Caving Association (BCA), itself the principal society in Britain for those interested in caving, with activities including provision of training and safety certification for cavers and managing access to caves. Although some UK cave-related research is carried out by academics, this tends to be restricted to archaeological investigations of caves that have served as human habitations, and to be focused more on the occupants than the caves themselves. In contrast, most cave exploration is undertaken as a leisure activity, under the auspices of clubs affiliated to the BCA/BCRA, this being indeed virtually the only field of Earth science where amateur investigators can continue to make significant discoveries. Many cave explorers are also affiliated with academic researchers, such as managers of dating laboratories; the synergy between these two groups is highly productive, having resulted for instance in the discovery and exploration in recent years of the vast Ogof Draenen cave system in South Wales, which probably dates back to the Early Pleistocene (e.g., Farrant et al., 2014).

    We formulate a theory combining the principles of scalar-tensor gravity and Rastall's proposal of a violation of the usual conservation laws. We obtain a scalar-tensor theory with two parameters ω and λ, the latter quantifying the violation of the usual conservation laws (λ = 1 corresponding to the General Relativity limit). The only exact spherically symmetric solution is that of Robinson-Bertotti besides the Schwarzschild solution. A PPN analysis reveals that General Relativity results are reproduced when λ = 0. The cosmological case displays a possibility of deceleration/acceleration or acceleration/deceleration transitions during the matter dominated phase depending on the values of the free parameters.

    Sonoluminescence is a process in which a strong sound field is used to produce light in liquids. We explain sonoluminescence as a phase transition from ordinary fluorescence to a superradiant phase. We consider a spin-boson model composed of a single bosonic mode and an ensemble of N identical two-level atoms. We assume that the whole system is in thermal equilibrium with a reservoir at temperature β-1. We show that, in a ultrastrong-coupling regime, between the two-level atoms and the electromagnetic field it is possible to have a cooperative interaction of the molecules of the gas in the interior of the bubble with the field, generating sonoluminescence.

  15. Quantitative characterization of nonstructural carbohydrates of mezcal Agave (Agave salmiana Otto ex Salm-Dick).

    Michel-Cuello, Christian; Juárez-Flores, Bertha Irene; Aguirre-Rivera, Juan Rogelio; Pinos-Rodríguez, Juan Manuel

    2008-07-23

    Fructans are the reserve carbohydrates in Agave spp. plants. In mezcal factories, fructans undergoes thermal hydrolysis to release fructose and glucose, which are the basis to produce this spirit. Carbohydrate content determines the yield of the final product, which depends on plant organ, ripeness stage, and thermal hydrolysis. Thus, a qualitative and quantitative characterization of nonstructural carbohydrates was conducted in raw and hydrolyzed juices extracted from Agave salmiana stems and leaves under three ripeness stages. By high-performance liquid chromatography (HPLC), fructose, glucose, sucrose, xylose, and maltose were identified in agave juice. Only the plant fraction with hydrolysis interaction was found to be significant in the glucose concentration plant. Interactions of the fraction with hydrolysis and ripeness with hydrolysis were statistically significant in fructose concentration. Fructose concentration rose considerably with hydrolysis, but only in juice extracted from ripe agave stems (early mature and castrated). This increase was statistically significant only with acid hydrolysis.

  16. Two-photon exchange interaction from the Dicke Hamiltonian under parametric modulation

    2018-02-01

    We consider the nonstationary circuit QED architecture in which a single-mode cavity interacts with N >1 identical qubits, and some system parameters undergo a weak external perturbation. It is shown that in the dispersive regime one can engineer the two-photon exchange interaction by adjusting the frequency of harmonic modulation to (approximately) 2 | Δ-| , where Δ- is the average atom-field detuning. A closed analytic description is derived for the weak atom-field coupling regime, and the system dynamics under realistic conditions is studied numerically.

    2014-01-01

    Unlike photons, which are conveniently handled by mirrors and optical fibres without loss of coherence, atoms lose their coherence via atom–atom and atom–wall interactions. This decoherence of atoms deteriorates the performance of atomic clocks and magnetometers, and also hinders their miniaturization. Here we report a novel platform for precision spectroscopy. Ultracold strontium atoms inside a kagome-lattice hollow-core photonic crystal fibre are transversely confined by an optical lattice to prevent atoms from interacting with the fibre wall. By confining at most one atom in each lattice site, to avoid atom–atom interactions and Doppler effect, a 7.8-kHz-wide spectrum is observed for the 1S0−3P1(m=0) transition. Atoms singly trapped in a magic lattice in hollow-core photonic crystal fibres improve the optical depth while preserving atomic coherence time. PMID:24934478

    Directory of Open Access Journals (Sweden)

    Federico Manuel Álvarez Gandolfi

    2017-12-01

    Full Text Available El presente texto se propone problematizar la aplicación del concepto de subcultura en el análisis de las dinámicas de construcción identitaria y producción simbólica que tienen lugar a partir del consumo fan de series animadas japonesas –anime– por parte de jóvenes habitantes de Buenos Aires. Dicho objetivo responde a que se considera que el abordaje de los grupos o colectivos de fanáticos en general, y de los otakus en particular –fans de los objetos de la cultura de masas proveniente de Japón–, en términos de subculturas, tiende a prescribirles cierta orientación de “resistencia”, influida por los estudios culturales británicos y la obra de Hebdige. A su vez, se entiende que en el campo académico de estudios sobre estos fans, aún en vías de constitución, suele predominar la utilización de dicha noción sin desarrollar una problematización teórico-conceptual al respecto. Las reflexiones que aquí se plantean, entonces, parten de una investigación propia sobre las identidades culturales que construyen y los sentidos que producen los otakus sobre sus prácticas de consumo, la cual asume una perspectiva comunicacional y socioantropológica, e implica la aplicación de técnicas de observación participante y entrevistas abiertas, tanto cara a cara como vía plataformas digitales, para reconstruir su propio punto de vista.

    Hypertrophy of the left ventricular myocardium is a common finding and can be reliably detected by echocardiography, CT and MRI. Common causes include diseases associated with increased cardiac afterload as well as primary and secondary cardiomyopathy. With the opportunity to determine functional parameters and myocardial mass precisely as well as to detect structural changes of the cardiac muscle simultaneously, cardiac MRI is the most precise imaging method for quantifying left ventricular hypertrophy as well as determining the cause and the exact characterization of the myocardial changes. It is mandatory, however, to create a flexible, individually adapted examination protocol. This review presents useful diagnostic algorithms in relation to different underlying pathologies in patients with left ventricular hypertrophy. (orig.)

    Kirjatöö lähtub Walter Benjamini (1892-1940)"Ajaloofilosoofilistest teesidest", seob need Eric Santneri (1955), Maurice Blanchot' (1907-2003), Jacques Derrida (1930-2004) ja Slavoj Zhizheki (1949) mõtetega, näidates selle kaudu tegelikkuse luhtumuslikku loomust ja fiktsiooni lunastavat otstarvet, võttes Christa Wolfi (1929) ja Mati Undi (1944-2005) teosed taustaks. Üritatakse vastata küsimustele, kuidas tuvastada ja kirjeldada võimalikkuste virtuaalset välja ajaloos, kuidas kirjeldada seeläbi fiktsiooni ja kuidas fiktsioon kandub tegelikkuse ontoloogilise konstitueerija rollist üle millekski ajaliseks - aja "loolisuse" ehituskiviks

  18. Cuando Oliver se dio un beso con otro niño, con su mejor amigo, Dick: lenguajes literarios y lenguajes violentos dirigidos a jóvenes LGBTQ en el sistema escolar

    Directory of Open Access Journals (Sweden)

    Mauricio Pulecio

    2015-04-01

    Full Text Available En este trabajo se analiza la forma en la que el lenguaje ofensivo contribuye al mantenimiento de la discriminación contra jóvenes LGBTQ en el sistema de educación básica. Se argumenta que este problema es global, aunque se analiza el caso colombiano como forma de articular una respuesta local. Se muestran los resultados de un trabajo de campo realizado en colegios de estratos altos de Bogotá, para ejemplificar las expresiones de odio que circulan en el entorno educativo. También, se estudian piezas literarias, especialmente del escritor homosexual Fernando Molano Vargas, y se aboga por su inclusión dentro de los currículos educativos. De esta forma, se intenta contraponer, a un lenguaje ofensivo, un lenguaje literario en el que se expresan formas de resistencia capaces de legitimar afectos no heterosexuales.

  19. Evolutionary algorithms and synthetic biology for directed evolution: commentary on "on the mapping of genotype to phenotype in evolutionary algorithms" by Peter A. Whigham, Grant Dick, and James Maclaurin.

    Science.gov (United States)

    Kell, Douglas B

    2017-01-01

    I rehearse two issues around the commentary of Whigham and colleagues. (1) There really are many more reasons than those given as to why natural evolution cannot reasonably find or select the 'optimal' individual. (2) A series of experimental molecular biology programmes, known generically as directed evolution, can use operators and selection schemes that natural evolution cannot. When developed further using the methods of synthetic biology, there are no operators or schemes for in silico evolution that cannot be applied precisely to directed evolution. The issues raised apply only to natural evolution but not to directed evolution.

    Philip K. Dick is considered to be one of the most unique and visionary talents in the history of American literature. Moreover, postmodern philosopher Jean Baudrillard regards him as "one of the greatest experimental writers of our era." Nevertheless, authoritative literary critics have undervalued Dick for a long time. This study aims at proving that his noteworthy work should be more focused in the field of literary academics. Do Androids Dream of Electric Sheep? is one of Dick's maste...

With minimal additional sealing of the chamber, we expect the Q to increase even more, and thus field levels for the same RF source power. Future studies need to determine leakage field levels, which will define maximum achievable field levels.

    Science.gov (United States)

    Faraoni, Valerio; Belknap-Keet, Shawn D.

    2017-08-01

    A new family of spherically symmetric inhomogeneous solutions of Brans-Dicke gravity is generated using conformal transformation techniques and the Fonarev solution of general relativity as a seed. The latter is mapped from the Einstein to the Jordan conformal frame and this Jordan frame version constitutes a new solution of Brans-Dicke theory. The Brans-Dicke scalar field self-interacts with a power-law or inverse power-law potential in the Jordan frame. The new 4-parameter family of geometries thus generated, which is dynamical and asymptotically Friedmann-Lemaître-Robertson-Walker, contains as special cases two previously known classes of solutions and solves also the field equations of f (R )=Rn gravity, which can also be seen as an ω =0 Brans-Dicke theory with a potential.

    The recently proposed extended inflation scenario is examined. Upper bounds on the Brans-Dicke parameter ω are obtained by requiring that the recovery from the supercooled regime be such that the presently observed Universe could have emerged. These bounds are well below the present-day experimental limits, implying that one must use models which have a potential to fix the present value of the Brans-Dicke-like scalar field. The implications for extended inflation in such models are discussed

  4. Heinrich Dieter Holland (1927-2012)

    Turekian, Karl K.

    2012-08-01

    Heinrich Dieter "Dick" Holland, who died on 21 May 2012, was responsible for major advances across several fields of geochemistry. He was born on 27 May 1927 and died just short of his 85th birthday. How Dick became a geochemist is an interesting story in itself. I first met Dick when we shared an office as graduate students at Columbia University in New York. He had attended Princeton University in New Jersey and graduated in 1946 with a chemistry major. He had arrived in the United States with his family from Germany in 1940. The family was of Jewish origin, and although Dick and his relatives were not strict practitioners, their fate in Hitler's Germany, dictated by the family's ancestry, would have been undesirable. Dick and his brother first went to England in 1939 to escape the future horrors that were sure to await them if they had remained in Germany. After their parents escaped to the Dominican Republic, Dick and his brother joined them there. With the help of friends, the family came to the United States from the Dominican Republic in 1940 (it was not unusual for immigrants to first come to a landing spot in the western hemisphere prior to admission to the United States).

  5. Evaluation of three cultivars of sweet sorghum as feedstocks for ethanol production in the Southeast United States

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Sweet sorghum has become a promising alternative feedstock for biofuel production because it can be grown under reduced inputs, responds to stress more efficiently than traditional crops, and has large biomass production potential. A three-year field study was conducted to evaluate three cultivars of sweet sorghum as bioenergy crops in the Southeast United States (Fort Valley, Georgia: Dale, M81 E and Theis. Parameters evaluated were: plant density, stalk height, and diameter, number of nodes, biomass yield, juice yield, °Bx, sugar production, and theoretical ethanol yields. Yields were measured at 85, 99, and 113 days after planting. Plant fresh weight was the highest for Theis (1096 g and the lowest for Dale (896 g. M81 E reported the highest stalk dry weight (27 Mg ha−1 and Theis reported the lowest (21 Mg ha−1. Theis ranked the highest °Bx (14.9, whereas M81 E was the lowest (13.2. Juice yield was the greatest for M81 E (10915 L ha−1 and the lowest for Dale (6724 L ha−1. Theoretical conservative sugar yield was the greatest for Theis (13 Mg ha−1 and the lowest for Dale (9 Mg ha−1. Theoretical ethanol yield was the greatest for Theis (7619 L ha−1 and the lowest for Dale (5077 L ha−1.

    Vinogradov, K. P.

    The publication of the Latin text of the treatise on the tides, ascribed to Robert Grosseteste, and its Russian translation. In 1952, Ezio Franceschini first edited and published the Latin text of the treatise. In 1966, Richard Dales presented a new edition where many defects of the previous edition were corrected. In Dales' edition, the treatise is entitled "Questio de fluxu et refluxu maris". The Latin text of the work used in the present publication repeats almost entirely that of Dales' edition. The Russian translation of the work is published for the first time and is provided with detailed commentary. In the introductory article the problem of authorship is briefly analysed, the time and place of the work's composition is considered. The necessary information concerning the life and works of Robert Grosseteste, Adam Marsh, and Adam Rufus is given in the closing part of the article - each of these masters can be considered as a probable author of the work.

    1994-01-01

    A conceptual radiometer design study was performed to determine the optimum design approach for spaceborne radiometers in low Earth orbit. Radiometric system configurations which included total power radiometers, unbalanced Dicke radiometers, and balanced Dicke, or as known as noise injection, radiometers were studied. Radiometer receiver configurations which were analyzed included the direct detection radiometer receiver, the double sideband homodyne radiometer receiver, and the single sideband heterodyne radiometer receiver. Radiometer system performance was also studied. This included radiometric sensitivity analysis of the three different radiometer system configurations studied. Both external and internal calibration techniques were analyzed. An accuracy analysis with and without mismatch losses was performed. It was determined that the balanced Dicke radiometer system configuration with direct detection receivers and external calibrations was optimum where frequent calibration such as once per minute were not feasible.

  9. Quintessence in low-energy effective theory

    Science.gov (United States)

    2018-01-01

    Considering a theory of Brans-Dicke gravity with general couplings of a heavy field, we derive the low-energy effective theory action in the universe of temperature much lower than the heavy field mass. Gravitational equations and the Brans-Dicke scalar field equation including an effective potential of the scalar field are obtained, which is induced through virtual interactions of the heavy field in the late-time universe. We find a deSitter cosmological solution stemming from the inverse power law effective potential of the scalar field and discuss the possibility that the late time acceleration of our universe can be described by means of the solution.

    Results on application of functional integration method to statistical physics systems with model Hamiltonians Dicke and Bardeen-Cooper-Schrieffer (BCS) are presented. Representations of statistical sums of these functional integration models are obtained. Asymptotic formulae (in N → ∞ thermodynamic range) for statistical sums of various modifications of the Dicke model as well as for the Green functions and Bose-excitations collective spectrum are exactly proved. Analogous results without exact substantiation are obtained for statistical sums and spectrum of Bose-excitations of the BCS model. 21 refs

  12. Change in density of NaCl:KCl crystal with Br impurities

    International Nuclear Information System (INIS)

    Ruiz-Mejia, C.; Riveros, H.; Cabrera, E.; Gally, M.

    1991-01-01

    The Dick and Das theory is revised in detail. We found that the errors in the repulsive energy expression and also for the Van der Waals energy are very important when the lattice deformation around a Br impurity is calculated. The right expressions obtained were used in order to obtain the displacements of the first and second neighbors around the impurity. The changes in density of the NaCl:KCl crystal obtained from these displacements are very large. The conclusion of this work is that the expressions given by Dick and Das are wrong (their formulas have not simple print errors) (Author)

  13. Obituary: Alan D. Fiala (1942-2010)

    Science.gov (United States)

    Kaplan, George

    2011-12-01

    Dr. Alan Dale Fiala, astronomer and expert on solar eclipses, died on May 26, 2010 in Arlington, Virginia, of respiratory failure after a brief illness. He was 67. Fiala had been a staff astronomer at the U.S. Naval Observatory in Washington, D.C., for his entire professional career, where he rose from a position as a summer intern to become the Chief of the Nautical Almanac Office, responsible for annual publications for astronomy and navigation that are used the world over. He retired from the observatory in 2000. Although a childhood case of polio affected his mobility for the rest of his life, he seldom let his physical constraints limit his activities, which were many and varied. Alan Fiala was born in Beatrice, Nebraska on November 9, 1942, the middle son of Emil A. ("John") and Lora Marie Fiala. Fiala's father was a postal clerk and Civil Service examiner. Fiala expressed interest in astronomy at a very young age. He contracted polio when he was 9. He graduated from Beatrice High School in 1960 with a straight-A average and went on to study at Carleton College. He received his B.A. summa cum laude after three years, in 1963, with a major in astronomy and minors in physics and mathematics. He was elected to Phi Beta Kappa, Sigma Xi, and Pi Mu Epsilon (mathematics). In 1962, Alan Fiala obtained a job as a summer intern at the Naval Observatory in Washington, working in the Nautical Almanac Office (NAO). He entered the graduate program at Yale University and continued to work summers at the observatory. He received his Ph.D. in 1968, under Gerald Clemence. His dissertation was titled "Determination of the Mass of Jupiter from a Study of the Motion of 57 Mnemosyne." After receiving his doctorate, Fiala became a permanent member of the Naval Observatory staff. Computers were just being introduced there and he participated in the automation of many procedures used to prepare the annual publications of the Nautical Almanac Office. One of his first assignments was

  14. Obituary: Richard B. Dunn, 1927-2005

    Science.gov (United States)

    Keil, Stephen L.; Dooling, David

    2007-12-01

    Dr. Richard B. Dunn, astronomer emeritus at the National Solar Observatory, died of a heart attack on September 29, 2005. He was recognized as one of the foremost experimental solar physicists. His innovative designs for telescopes and instruments led to many important discoveries in solar physics. Born in Baltimore, Maryland, in 1927 and raised in Minneapolis, Minnesota, Dick's parents were Dr. Halbert L. Dunn and Katherine Brandner. Halbert (MD, Ph.D., F.A.P.H.A.) was an physician who became Chief of the National Office of Vital Statistics, Public Health Service. He published a paper "High Level Wellness for Man and Society" that became the founding paper of the field of wellness health care. After their divorce in 1942, Katherine moved to New York and became a social worker. Dick had two older brothers who died before him, Halbert (born in 1921, who became a civil engineer) and Robert (born in 1924, who became an architect). Dick earned a BS in mechanical engineering and an MS in astronomy at the University of Minnesota. At the end of World War II he served in the United States Army in Japan. For his master's degree, Dick undertook the design and construction of a Lyot-type birefringent filter for observations of solar prominences. This early work led to his acceptance at Harvard, where Professor Donald Menzel encouraged him to continue his work with the 15-inch Cambridge telescope. In 1951 he conducted part of his doctoral thesis work at the fledgling Sacramento Peak Observatory in southern New Mexico. The observatory director, Dr. John Evans, was impressed with Dick's outstanding instrumental talents and invited him to join as one of the first scientific staff members. During his first few years at Sac Peak, Dick developed two more birefringent filter systems including one with an integrated coronagraph. With this system, he produced the best prominence and spicule observations ever obtained. Dick's career was dedicated to obtaining solar observations of the

    The phase of a frequency standard that uses periodic interrogation and control of a local oscillator (LO) is degraded by a long-term random-walk component induced by downconversion of LO noise into the loop passband. The Dick formula for the noise level of this degradation is derived from an explicit solution of an LO control-loop model.

    Brans–Dicke scalar–tensor theory provides a conformal coupling of the scalar field with gravity in Einstein's frame. This model is equivalent to an interacting quintessence in which dark matter is coupled to dark energy. This provides a natural mechanism to alleviate the coincidence problem. We investigate the dynamics of ...

    In past issues of this journal, the late H. R. Crane wrote a long series of articles under the running title of "How Things Work." In them, Dick dealt with many questions that physics teachers asked themselves, but did not have the time to answer. This article is my attempt to work through the physics of the crystal set, which I thought…

  20. Obituary: Richard D. Schwartz (1941-2011)

    Science.gov (United States)

    Wilking, Bruce

    2011-12-01

    Richard D. Schwartz, Professor Emeritus of Astronomy, died at his home in Sequim, WA, after a nearly 3 year battle against pancreatic cancer. Richard was born in Pretty Prairie, Kansas. He was active in sports and band and graduated in 1959. After completing a BS at Kansas State, and a Master's degree in Divinity at Union Seminary in NY, he further studied astrophysics, receiving his doctorate from University of Washington in 1973. When Dick arrived at the University of Missouri-St. Louis in 1975, he was the only astronomer in the Department of Physics. He built the astronomy program and initiated the B.S. in physics with an astrophysics option that the majority of physics majors choose. Dick was a wonderful teacher and provided outstanding leadership to the campus. He designed and provided oversight on the construction of the campus observatory that was completed in 1981. Since that time the observatory has served as both a teaching and research facility. It is also used for monthly public open houses that draw hundreds of people annually to the campus to view the moon, stars, and planets. Upon his retirement in 2003, the Board of Curators approved naming the campus observatory the "Richard D. Schwartz Observatory" in honor of his distinctive service to the University of Missouri-St. Louis. Just as important as Dick's service to promote public interest in astronomy was his effort to make the campus observatory a research facility. Dick equipped and maintained the observatory with state-of-art detectors that allowed students to get their first taste of scientific research. From 1991-2003, he managed the campus program for the NASA/Missouri Space Grant Consortium and mentored over 30 research students in projects at the observatory. Some of the results have been published in astronomical journals. Many of those students went on to graduate schools and several have achieved tenure and distinction at major universities. In addition to Dick's service to the University

    Tropospheric ozone lidars are well suited to measuring the high spatio-temporal variability of this important trace gas. Furthermore, lidar measurements in conjunction with balloon soundings, aircraft, and satellite observations provide substantial information about a variety of atmospheric chemical and physical processes. Examples of processes elucidated by ozone-lidar measurements are presented, and modeling studies using WRF-Chem, RAQMS, and DALES/LES models illustrate our current understanding and shortcomings of these processes.

    Full Text Available Considering a theory of Brans-Dicke gravity with general couplings of a heavy field, we derive the low-energy effective theory action in the universe of temperature much lower than the heavy field mass. Gravitational equations and the Brans-Dicke scalar field equation including an effective potential of the scalar field are obtained, which is induced through virtual interactions of the heavy field in the late-time universe. We find a deSitter cosmological solution stemming from the inverse power law effective potential of the scalar field and discuss the possibility that the late time acceleration of our universe can be described by means of the solution.

They address Washington Cucurto’s writing device with respect to the “negro”’s golden dick that the narrator/character Tyson Grande/Washington Cucurto/Norberto Vega implants into himself in Las aventuras del Señor Maíz (2005. We argue that such chirurgical and body prosthesis exhibits forces (in a Deleuzian sense which govern all of Cucurto’s/Vega’s production: social, economic, sexual and Latin American cultural forces. The golden dick is, then, a poetic condensation which exhibits the writing machine as a melancholic beast in whose body forces in struggle for literature become destabilized.

  19. The Aquarius Ocean Salinity Mission High Stability L-band Radiometer

    The NASA Earth Science System Pathfinder (ESSP) mission Aquarius, will measure global ocean surface salinity with approx.120 km spatial resolution every 7-days with an average monthly salinity accuracy of 0.2 psu (parts per thousand). This requires an L-band low-noise radiometer with the long-term calibration stability of less than or equal to 0.15 K over 7 days. The instrument utilizes a push-broom configuration which makes it impractical to use a traditional warm load and cold plate in front of the feedhorns. Therefore, to achieve the necessary performance Aquarius utilizes a Dicke radiometer with noise injection to perform a warm - hot calibration. The radiometer sequence between antenna, Dicke load, and noise diode has been optimized to maximize antenna observations and therefore minimize NEDT. This is possible due the ability to thermally control the radiometer electronics and front-end components to 0.1 Crms over 7 days.

  20. Dynamics of a trapped two-level and three-level atom interacting with classical electromagnetic field

    The dynamics of a two-level atom driven by a single laser beam and three-level atom (Lambda configuration) irradiated by two laser beams are studied taking into account of the quantized center-of-mass motion of the atom. It is shown that the trapped atom system under appropriate resonance condition exhibits the large time-scale revivals when the index of the vibrational sideband responsible for the atomic electronic transition is greater than unity. The revival times are shown to be dependent on the initial number of vibrational excitations and the magnitude of the Lamb-Dicke parameter. The sub-Poissonian statistics in vibrational quantum number is observed at certain time intervals. The minimum time of interaction for which the squeezed states of motional quadrature are generated is found to be decreasing with the increase in the Lamb-Dicke parameter

    The maximum size of a cosmic structure is given by the maximum turnaround radius—the scale where the attraction due to its mass is balanced by the repulsion due to dark energy. We derive generic formulae for the estimation of the maximum turnaround radius in any theory of gravity obeying the Einstein equivalence principle, in two situations: on a spherically symmetric spacetime and on a perturbed Friedman-Robertson-Walker spacetime. We show that the two formulae agree. As an application of our formula, we calculate the maximum turnaround radius in the case of the Brans-Dicke theory of gravity. We find that for this theory, such maximum sizes always lie above the ΛCDM value, by a factor 1 + 1/3ω, where ω>> 1 is the Brans-Dicke parameter, implying consistency of the theory with current data.

    Quantum information theorems state that it is possible to exploit collective quantum resources to greatly enhance the charging power of quantum batteries (QBs) made of many identical elementary units. We here present and solve a model of a QB that can be engineered in solid-state architectures. It consists of N two-level systems coupled to a single photonic mode in a cavity. We contrast this collective model ("Dicke QB"), whereby entanglement is genuinely created by the common photonic mode, to the one in which each two-level system is coupled to its own separate cavity mode ("Rabi QB"). By employing exact diagonalization, we demonstrate the emergence of a quantum advantage in the charging power of Dicke QBs, which scales like √{N } for N ≫1 .

  4. Reply [to “Is the AGU headquarters bond issue really a boon?”

    Science.gov (United States)

    Ostenso, Ned A.

    Dick Von Herzen raises two issues that affect us all: our Union's economic health and the role of a headquarters building in our financial portfolio. These issues deserve the widest possible ventilation among our total membership, and I am grateful that Dick's comments offer yet another opportunity to address them. I assume this responsibility in my capacity as chairman of the ad hoc Real Estate Committee and as the “continuity” member of the Budget and Finance Committee.In responding, I want to make two salient points: the AGU is financially healthy and the role of the headquarters building in our asset mix is established by formal policy. By extension, the new building is derived from a series of explicit Council decisions.

    2012-01-01

    This volume is devoted to the dynamics and diagnostics of solar magnetic fields and plasmas in the Sun’s atmosphere. Five broad areas of current research in Solar Physics are presented: (1) New techniques for incorporating radiation transfer effects into three-dimensional magnetohydrodynamic models of the solar interior and atmosphere, (2) The connection between observed radiation processes occurring during flares and the underlying flare energy release and transport mechanisms, (3) The global balance of forces and momenta that occur during flares, (4) The data-analysis and theoretical tools needed to understand and assimilate vector magnetogram observations and (5) Connecting flare and CME phenomena to the topological properties of the magnetic field in the Solar Atmosphere. The role of the Sun’s magnetic field is a major emphasis of this book, which was inspired by a workshop honoring Richard C. (Dick) Canfield.  Dick has been making profound contributions to these areas of research over a long and pro...

If Melville in Moby Dick sets up an anthology of whaling, Eugenides builds his collection of Greekness.
